This diecut was made in two sizes and at least one variant. This appears to be the smaller of the two based on the teeth. (You can see the difference in the teeth with the larger size on page 171.) The variant is that this size was also produced with a printed paper backing for the eyes, nose and mouth. This variant, also shown on page 171, is exceedingly rare. I've only seen it one time and I bought it straight away.
