This First Day Issue (FDI) cancellation stamp & envelope debuted at the 2006 San Diego Comic Con. It is autographed by Sheldon Moldoff, the inker of the image that appears on the stamp (Curt Swan provided the pencils). The FDI measures approximately 3 3/4 by 6 3/4 inches, is in nm/mint condition and will be shipped with the utmost care. Please note- the signature is real. It is the actual, hand-signed signature of Moldoff. It is not a pre-printed image on the envelope.
