I can't find an Autobot symbol on Voyager Optimus Prime. There are none on the packaging pictures either. This is pretty weird considering the other figures have prominent symbols, often visible in both modes. Now, given OP's robot mode, no-one will mistake him for anyone else, but I thought this was very strange.

There is also a small indentation on his right shoulder like something should be in there. Have I just missed the symbol or is everyone else's like this?
