12x21.5" poster shows young magician and Gilbert Mysto Magic devil logo. This is a stock poster which has not been filled in as to the performer nor has a date sheet been pasted on the bottom as instructions suggest. Dated 1917 and was included in early Mysto Magic sets to promote your performance after you had perfected your tricks. Heavy fold lines as issued to fit inside the box. Some lt. paper loss along these fold lines and a few chips on upper and side corner. It has been tacked at two upper corners on black foam core for a nice appearance. Fine.
