From Authentic Police Cases #23 (1952):
"Snake Bow-Tie"? What the...?
I wish I knew how that worked...
If I bought this, I would be so ticked off if the snake didn't really have venom dripping from its fangs, like the pictures depict.
Hmmm, venom dripping from the fangs...that would be a cool trick for the Joker to use, the venomous snake leaping from the bow-tie...a snake genetically-engineered to produce Joker venom!!
That is why I'm not allowed to write Batman/Jimmy Olsen crossovers...
