The embossed metal team logos make a nice collectible by themselves. Here is a near set of all the labels:
Based on scanning ebay for pictures of the different teams, it looks like you can still find these Decanters without too much difficulty as I was able to find auctions for just about every team.
Unfortunately Avon did not produce an MLB set. I would have enjoyed trying to collect a set of the MLB embossed labels.
