If you collect this team or player you probably don't have this card!!!
This very rare 1988 Topps Test Issue Cloth card of Tony Gwynn (All Star) has been graded ISA 10 (GEM MINT).
The card is from a 121 card set that was actually an "Experimental Issue" produced by Topps and was never released. The set is printed on a thin gauze fabric which supposedly expanded into a sponge when submerged in water. The backs are blank.
ISA is a new grading company that has quickly attained a great deal of respect within the industry. We stand behind their grades 100%.
