I've always been a Detroit fan, from '84 on, and would place extra value on anything associated with the team. By 1987 I was well aware of the 100 year old Detroit cards issued by Goodwin & Co. and began collecting Detroit Old Judges (although it was a very slow go). I would eventually drift away from the hobby but came back with a vengeance in 2003 with strictly a Detroit 19th century focus (that is one way for a Detroit collector to avoid the "Cobb" issue).
Its been a blast but now find it difficult to locate the remaining items I need so I've branched out to other things (N333 Newsboys, 19th century cigarette packs, and coupons). I now live in Iowa so I also keep an eye out for cards depicting players from Iowa (here is one for you Craig - a tough team card).
