Castle is said to have loved animals, particularly the ones he often saw around his family’s small farm. While birds are commonly featured in Castle’s artwork, he rarely made constructions of other animals.

This pram, or baby carriage, demonstrates Castle’s exacting nature when assembling constructions. Numerous layers of cardboard give this work added dimension, and thick twine and string woven through the cardboard provide structural support.

These two delicately constructed figures feature separate pieces of paper for each element of clothing, including socks, shoes, shirts and coats. They also appear as drawings in one of Castle’s handmade books.

Castle seemed fascinated by the structure of coats. This coat reveals a tremendous amount of care and attention to detail. The buttons line up perfectly with adjacent holes, with one tucked just under the folded collar, and the color belies the effort required to saturate this construction with dark blue.

These rare, three-dimensional sculptures are surrounded with squares of thick paper carefully sewn to each vessel. These paper squares are also seen on 2-D constructions that depict volumetric forms such as pitchers and bowls.

This construction with hand-colored geometric shapes carefully sewn to a cardboard sub-structure probably depicts the patterned wallpaper often seen in Castle’s drawings of interior living spaces.
