It may not be completing three base sets, but this small PWE trade with TCDB member Metch35...
These include the last two of three Jays from the 2022 Panini Absolute retail base set, which are the two big names you would expect if you were picking three Jays for a 2022 base set.
With one base add for 2021 Topps, that winds up this PWE. I did add the missing base cards to my want list for 2021 Topps as I figure they may come in this way...one or two in many trades, instead of full trades for missing one. Time will tell if it continues.
