I love this idea! So many cards to collect just like it would have been during this time. LOL.
The only problem I am having is putting the cards on the poster, it keeps telling me I can't put the SciFi Card on the SciFi poster, same with the other three, and the board game shelving unit. Is there a fix for this? It's not all the cards, just about 1/2 of them that I have come across and tried to add.
