I think it was from that GTS National Hobby Shop Day promotion. There was a thread about the 2019 one but no one mentioned here last December. I forgot about it too. I'm going to stop by a sports card shop today and see if they still have anything - probably not.
Originally posted by Tommy C: I didn't know this until now, but at participating comic stores in December, there was a particular event in which these were given out:
Rick and Morty 3 promo P9
Steven Universe P8
