[The Detroit Collector]

Hello.
This past weekend I bought my first m101-1 Sporting News Supplement through the REA auction. I can't wait to receive it.
The set from what I've seen online is absolutely gorgeous and is loaded with hall of famers.
I know this is a very rare set. I believe the pieces would only be issued on a single day for each player.
I am trying to learn as much as possible about this set.
Does anyone here have some knowledge of the set? Or have some resourceful websites I can check out?

Thank You
