The Energon Pub

Could someone please show me where I can find good sized images of all the Cybertronian symbols? I'm in the process of carving a series of rubber stamps for my letterboxing hobby (http://www.letterboxing.org). They're stamps of various symbols from the Transformer mythology. I've carved the Autobot, Decepticon, Maximal and Predacon symbols. The ones I'm looking for in particular are the Vehicon and Mini-con symbols.

I would greatly appreciate if anyone could direct me to where I can find the various symbols.

Thank you all so much! You have been a tremendous help! I really do appreciate it!
