I've collected autographs for about 5 or 6 years now. My first hobby was collecting comic books, which I've done since I was about 5 years old in 1973. Recently, I've started going to comic shows and getting many of my comics autographed by the artists and writers. I'm very happy with the results so far.
The artist/writer guests at comic shows usually sign your items for free, and seem to be thrilled to casually chat with fans. Also, they typically have original drawings and prints available for purchase at very reasonable prices.
It's a real thrill to meet the people who wrote and drew comics which have given me so much pleasure over the years. And, I find signed comics to be very compelling and dynamic additions to my comic and autograph collections.
