This sub-genre, Whitney fences, is a particular favorite of mine. This was made in the later 1920s out of light-weight cardboard delicate enough that you assemble then disassemble at your peril. Bottom line: Put it together the way you want it and never touch it again except to gently move it to dust underneath. (That is assuming you dust at all!) Different from so many Whitney designs, each of the four sides is completely different. Somewhat later they got lazy and either had 2 and 2 designs or four identical sides. The last thing to look for when buying these fences is that all the tabs are present. This example meets the test.
