That's correct. I have obtained this card at the Boston Red Sox vs. Atlanta Braves game June 6th (1999 I believe) at Fenway Park. The card is a 1988 Donruss #539 (Greg Maddux in Cubs Uniform). Card is in great condition and Greg signed this for me in blue marker. The autograph is sweet and is on the light part of the card, making it look really nice. For $5 delivered, you could own this! Let me know!!!
