Purchased on eBay, April 2012.
I normally do not buy autographed cards on eBay, but this one looked legit. I have gotten Chelios' autograph several times in person back in the day, and own a few certified autos. It is one of those autographs I can recognize because I've seen it enough times throughout the years. As you can see, this is nicely signed in blue Sharpie marker.
This card is from the 1990-91 Chicago Blackhawks photo album, and shows Chelios in his first season with the 'Hawks. The cards were issued in book form, but many people would cut them out to get them autographed.
