Superman #75 Polybag SS CGC 9.8 Dan Jurgens Sketch Signature Series 1993. Up for sale is a copy of the poly-bagged edition of Superman #75 from 1993 signed with a Superman sketch by writer and artist Dan Jurgens and graded 9.8 (NM/MT) by CGC under its Signature Series label. This issue culminates in the “death” of Superman. The CGC case is in great shape with no cracks. You never know, I might just take it, or at least make you a counteroffer. For those of you unfamiliar with Signature Series, the Signature Series label takes the place of a certificate of authenticity, and with it you know that a certified CGC witness saw the comic being autographed by the person indicated, and immediately afterwards took the comic into his possession so that there is no doubt the autograph is authentic. In the case of multiple autographs signed at different times, a CGC witness will only release the signed comic at the time it is to be autographed by another person, and then takes it right back. Note that the picture is of the actual comic for sale and not just some “stock” photo.
