I bought 2 of these for my sons. I have to admit, I was pretty disappointed by the size of the dinosaur on the inside of the shirt. It's does NOT cover my son's whole face like in the picture. It's pretty small, about 3" by 4". Both size shirts have the exact same size dinosaur, it doesn't get proportionally bigger based on the shirt size. Just know that the dinosaur is SMALL before you buy this shirt!
