Baby Mario Nintendo Playing Cards
Nintendo Super Mario 3 Rubber Figurines
German seller kr155e has some nice Virtual Boy rarities for sale. Highlights include including VB Playing Cards (of which a similar set recently sold for $224) and FlashBoy (Flash Cart). I’ve been told the seller also has has SD Gundam Dimension War and some more VB rarities for sale, but currently not on eBay though. Might be worth asking if the VB is your thing.
