Hey everybody, stumbled upon these Meiji cards in one of my binders and can’t seem to find them on ebay or anywhere on Bulbapedia, just curious if anyone can tell me what they are/if there’s a market for them! Thanks, and sorry for the poor photo quality. 
Can’t say I know much. I do know you’ve got a buyer though for that HP 50 Pichu @pichufan
He should also be able to help explain a little bit

I also have a lot of these but unfortunately I have no idea where they come from.
Like @mjisaacs mentioned I’d be happy to take the 50HP Pichu off your hands if you’re willing to sell (or trade for one of the other cards I have).
