5.75x5.75" thin artboard has original bw pen and ink artwork w/image area measuring 2-1/8x2-1/8" and art has "D.C. Inc" copyright paste-over while name right of image has been hand-lettered. Production notations below art indicate that copyright strip was incorrect but appears to have been corrected according to information in notes. Top also has some sizing production notes in pencil. Artboard has scattered small spots of staining. Fine overall, but art is Exc. In addition to artboard, there is a separate 5.75" square sheet of onionskin paper w/red/fleshtone colors which, when placed over the bw art, provides the colors for the finished button. This has production note noting that red color should be blue and Superman's "Scarf" should be red. This sheet has been mounted to acetate sheet w/double-sided tape. Paper has quite a few thin ripple lines but these do not detract greatly. Comes w/example button w/blue version w/corrected D.C. Inc. copyright. Art is unique. 86 Pep pins were produced in this set and this is far and away the best to have the original art for. All vintage Superman merchandise art is extremely rare and highly sought after. A truly unique piece for the Superman collector.
