Unless this is a front/back fabrication (perhaps a modified E135 Collins-McCarthy) from a card MD which got past the grading company, this Meadows is a new addition to the E121-80 checklist. Not just a team variation, but a completely new card unknown before now:

I think the winner got an incredible bargain. It amazes me what is still undiscovered out there...this set has been hanging around 90 years, and no Meadows until now?
