Page "Wallace and Gromit" Paragraph 10

In the first photo shown on The Curse of the Were-Rabbit, it was revealed that once, when Gromit was little, Wallace had much more hair and a beard.

On the photo that shows Gromit's graduation at Dogwarts, he had lost his beard, but still had a little hair, in the form of little patches just above his ears.

The reason behind Wallace's loss of hair is unknown.

As shown in The Wrong Trousers, he still uses a hair-dryer.

In a " Matter of Loaf and Death ", when Wallace is talking to Gromit, a picture is seen behind Gromit of Wallace with a brown beard and brown hair.
