Three sweet old crayon drawn airplanes, from a larger set of plane drawings by one boy with an airplane obsession, done in the 1930s I believe. The large one is of the LUSAC-11, an early American two-seat fighter aircraft of French design, commissioned and built in the United States during World War I. I especially love the little flyer in profile on the one I've got turned on its side.
Large one in this group measures 11 1/4" x 6 1/2". Smallest 3 1/8" x 3 13/16". Overall good condition, with a little age toning and few small tears as pictured.
