I have the cane that came out.
replica right? - looks a little thick between your fingers and head.
I have a Riddler collection going of actual props - own his green jumpsuit, both the question mark cane and the skull cane, his gloves he uses briefly at Wayne Manor enterance/lair and soon a batbomb.
If anyone knows the location of any other actual Riddler props please let me know
dude, show some pics! :love
