Crossposted on Nintendo Age. Thought I'd try selling on the forums first before taking them to Ebay.
Peek-A-Boo and Hot Slots were former rentals and their instruction cards are reproductions. As you can see from the pics, there's rental stickers and sticker residue on them. Could probably be cleaned up though but I never tried. Bubble Bath Babes is in excellent condition though and it includes the original instruction card.
To be honest, I haven't followed NES prices much lately, so I'm not sure what the going price is on these. So right now I'd just like to take offers and go from there. I really would like to sell them all as one set but if I can find people willing to buy all 3 separately, I'd consider splitting them up. I'm not interested in selling the boxes, carts or cards separately though, so please don't ask. No trades either.
