I did the same thing - ordered all variants, then a second of the "regular attire". The second joker will be in his board shorts on the surfboard diorama I also ordered. I'm thinking the other variants will be in order of clown joker, ledger bank robber joker (masked head), my custom Nicholson joker (still in progress), the inart purple coat joker, then the baseball joker. The inart jail joker will be off by himself, just because the cell diorama is so big.
Eventually, I'll display all of the other mars 1966 villains with HT batman & robin around the batmobile. I've dreamed of that display for years
It's a great time to be a 1966 batman fan, but it would be a PERFECT time if the economy was better
