7x11.75x4" tall by Bailey of Hollywood. 1950s. "Space Patrol" logo with rockets and planet graphics. This hat has been signed by cast on brim but they signed their character names, not real names. However, each is in their hand and matches perfectly with signatures seen on the cast photos folder premium issued by Dr. Ross dog and cat food. Of the 5 main characters, only Buzz Corey has not signed. Signatures include: Carol, Cadet Happy, Major Robertson and Tonga. Only such signed item we've seen. Hat has scattered areas of moisture staining, not affecting brim of hat. Fine overall with Exc. signature areas. Comes with Hake's COA.
