This is Gordon, not Thomas the Train. He's the "big blue engine." The customer's son was turning four on his birthday so she wanted a "4" on the cookie instead of her son's name which is what I usually do for Thomas cookies. Gordon also happens to be the number "4" engine. I think he came out fairly well and thought the crow's feet was a major differentiator in distinguishing the difference between Thomas and Gordon!
You can see his friend Thomas (the cookie) here.
