It’s one of the three Manhole promos. The other being Hoppip and the Manhole card itself. All information I know about them can be found spread in the three pages of this thread: www.elitefourum.com/t/any-information-on-these-cards/12600/1
Nice collection posts thus far btw. Love the individual highlights of these unique items. 
Keep up the great work.
