“Big Brutus” in West Mineral, Kansas, is a retired electric coal mining shovel listed in the National Register in 2018 as an object for its statewide significance under Criteria A and C in industry and engineering, with a period of significance of 1962 to 1974. Big Brutus is the centerpiece of a museum of Kansas mining history. The Criteria Bulletin provides that objects relocated to a museum are inappropriate for listing in the National Register; however, Big Brutus is an exception to this prohibition as it is not only sited in a setting appropriate to its significant historic role, the location and setting are the land once worked by Big Brutus (with the land itself a contributing resource).

The citizens of Enterprise, Alabama, erected the Boll Weevil Monument in 1919 to commemorate this insect anti-hero for its role in “diversifying the local economy by abolishing one-crop agriculture” (Boll Weevil Monument Registration Form, p. 3). Although created as a commemorative property, the monument has acquired its own significance due to the passage of time.

The Dine-A-Ville Dinosaur, a 40-foot-tall anthropomorphic pink dinosaur with a curving neck, toothy smile, and long lashes, once welcomed visitors to a local motel/cafe in Vernal, Utah. Erected in 1958 of wire mesh and fiberglass resin on a metal frame, this monumental roadside sculpture was moved in 1999 from its original location to its current location, where it now welcomes visitors traveling from the east and Dinosaur National Monument. Its new location has the orientation, setting, and general environment comparable to those of the historic location and compatible with the property's significance.

The Encinitas Boathouses are "tied to what is today regarded as a classically Californian historical movement of strange and unusual vernacular architecture” and as such are “an exceptionally rare, well-designed and well-crafted example of Fantasy-themed residential style from the apex of the 1920s and 1930s Programmatic Fantasy Architecture craze” (Encinitas Boathouses Registration Form, pp. 12, 26). These two “celebrated buildings within the City of Encinitas, symbolizing the historic beach town’s close connection to the sea” were listed in the National Register in 2019 under Criterion C for their local significance in architecture, with a period of significance based on the year of their construction, 1929 (Encinitas Boathouses Registration Form, p. 12).

Grandma Prisbrey's Bottle Village in Simi Valley, California, is a property that embodies the characteristics of California folk art. This 1/3-acre historic district includes 17 structures—7 of which are contributing resources—built by Tressa “Grandma” Prisbrey with minimal assistance, using bottles placed horizontally in mortar to create buildings to house her various collections of common (and uncommon) items, including lipstick cases, pine cones, horse shoes, shells, gourds, toothbrushes, dolls, and 17,000+ pencils. The property was listed in the National Register in 1996 as a district for its statewide significance under Criteria B and C in the areas of art, architecture, and landscape architecture.

The Olson House in South Cushing, Maine, is a well-preserved vernacular Greek Revival Style farmhouse, with several outbuildings. However, it was listed in 1993 not under Criterion C for its architectural significance but rather under Criteria A and B for its role in art. Artist Andrew Wyeth had unrestricted access to the house and was given a room to work in on the third story, and the property’s period of significance tracks with Wyeth’s relationship with the Christina and Alvaro Olson, from 1939, when he first met the Olsons, to 1968, after both Olsons died. The Olson House is open to the public, who can examine the property from the same views that inspired Andrew Wyeth for almost fifty years.

The Plaza Tower in New Orleans, Louisiana, is a 33-story office building, with a distinctive, cantilevered “hat.” It was listed in the National Register in 2012 under Criteria C; however, it was not listed for its significance in architecture but rather in engineering, for its innovative foundation system. Construction began in 1964 and employed a new, patented civil engineering technology, the Brunspile sectional pile and wedge connector. This system of pre-cast pilings allowed for deeper penetration of the deep alluvial soils that characterize the New Orleans area and provided the necessary support for taller (and heavier) buildings. Its successful use in the Plaza Tower project pioneered the method for subsequent tall buildings in the city as well as other areas with similar soils.
