It was signed as part of an official signing and sold on one of the Home Shopping Networks in the early 90s. It comes with a COA from a reputable memorabilia company from New Jersey. Obviously they didn't all sell, so some guy on ebay was selling the overstock for a $7.50 Buy-It-Now. The signatures are all certainly authentic. This is quite a deal and makes a nice display piece.
I really like it when I can combine my two hobbies of comics and autographs.
