Each bookend weighs just under 2 pounds.
There is a hole drilled measuring just less than 1/4" in diameter atop each bookend's head.
I like the idea of sculpture dressing bookshelves, while functioning to separate volumes of knowledge.
"Unknown artist" is appropriate when a work of art is unsigned and a supported opinion about who made it is not available (on Savvy Collector).. "Attributed to" precedes the name of an artist when information suggests that it likely was made by that artist (on Savvy Collector).
