Abstract
Abstract A folding easel is provided wherein the two uprights of the easel are provided with complementary mortises or notches which hold the two uprights together at a fixed angle when the two uprights are held together with a clamp. The clamp means can be released, allowing the two uprights to be held in a parallel relationship for transportation or storage.
