Looking to trade for (or buy) (1) Tim Watkins 1990 CMC 28 Autograph

I am looking to trade for (or buy) an autographed Tim Watkins1990 CMC 28 in blue Sharpie. This card is from the large 800+ card set with the yellow stat side, not the team set card with the green stat side.

Would prefer to see a pic as well.

Can trade for another 1990 CMC duplicate I may have if collecting this set.
Looking to spend no more than $10. Willing to send cash, along with a SASE.
