I only have stamps of Hitler from his right side of the face. Are there any others?
There are, indeed. Unless someone beats me to it, I'll post some photos when I get home. There are a few I can think of that show his left side.
One shows him (torso on up) standing at a podium (1939), another shows him with another person (1941 profile of heads only), and one other is an unadorned profile shot (1941). There may be more, but these are what I remember off the top of my head.
There's also the souvenir sheets from 1937 that are 3/4 profile shots of the right side & front of his face, and a stamp showing him patting a little girl on the head.
