1999 Fleer Mystique Football Forum

This week I've been working on 1999 Fleer Chicago Bears and there are three Mystique versions shown here including Gold and Masterpiece. I have found and purchased the Mystique and Mystique Golds that I wanted but when I search for Masterpiece I find no NFL cards at all for sale from this set. This takes me back to my recent post inquiring about print quantities. Do any of you know whether this is a short print or rare set? I'm surprised to find nothing in my search. 

They were 1 of 1's.  You probably won't find them.

Here's one of the Mystique baseball Masterpieces

Yeah I actually did just find a few on eBay, they're 1/1 and high priced. I guess I won't be adding any of those to the mix. 

I came across a pack hidden away. Scanned in images front/back but in the pack? 4 cards, 1 being covered front & back. Here's what it looks like & is a peel-away. I've left it as-is, could it be what you were talking about or just their way of adding an insert to a pack?
