Cardpocalypse challenge - Day 1

So it seems to me that the last week or so has been a little slower on the blog-o-verse in terms of total posts.  So just in time, here comes a weeklong posting challenge courtesy of Tim at Cardpocalypse!  Basically, the idea is that you can post along with him, day by day on a simple theme.  Tim isn't looking to enforce when or how we post these things, but I am going to try to follow his basic suggestion of one post a day (image stolen blatantly from Cardpocalypse):

Some of these might be a little hard for me, but I'll do my best.

Day one is 'Favorite card acquired during quarantine'.

---

So I have already posted all of the cards that I have received during the quarantine, except a couple that just came in the mail.  And I don't want to do a rehash of something I already posted.  But there is one card that I received that I have not posted because I don't know who it is from.

I got a PWE about 2 weeks ago with no return address and no note.  Inside was one card, and it was pretty cool:

Now I am not the biggest fan of randomly throwing together 2 players on a card for achievements that are not even related.  But hey, Ripken and Gwynn!!  And a pretty well put together look too.

So in the time since I received the card, I tried to find the appropriate place in my collection for this.  Is it a Gwynn card?  Is it a Ripken card?  Well, I have just the place for these things.  I have a section for multi-player cards, and to be honest, I have some pretty cool looking cards in there.  So I headed there only to find that I already have this card!!  Dupe!

So I guess I could put one copy with the Ripkens and another with the Gwynns.  But I don't think I will.  The card fits best in the multi-player area.

Now the only mystery is, who sent me this card?????  If you are out there and reading, let me know!  And thanks!
