Quick idea:
I somewhere in the DC section mentioned that my movie accurate Joker socks cloth finally arrived. Protos will be done and shown (I wanted to finish the socks yesterday but time is short) by the end of the week. Pattern is always the same but different sizes, I will show the socks to decide which pattern is the best to use for the final versions.
Whoever got a Bobby C Joker head will get 1 pair for free as soon as I receive my final cloth (which will be in 2-4 weeks). These guys only have to cover the postage costs.
This way we find out how many are around and I will finally get the address of Chris Nolan.
