2x5x1" deep wood block w/metal printing plate that features logo "Flying Superman" plus image of the plastic toy issued as a premium by Kellogg's in 1955 (not the larger flying Superman figures found in lot #2044). The image of the toy is the same that appears on the premium's instruction sheet, however, the printing plate also includes a 25¢ price circle. Comes w/7x9" sheet of tan paper w/printing block image done in red and as the sheet has aged, this was obviously done long ago. Printing block has general wear from use but VF. Possibly unique.
