I'm in my Prime

This is a drawing I made as part of a Christmas present for a friend of mine. I wanted to make something for this person, because he is a man who I'm quite sure has everything that can be bought with money, and then some. So seeing how he is a big transformers fan, I decided to make a drawing of him and Optimus Prime, and print it onto a T-shirt.

The pun in the title should go without mentioning.
