Another few items so random that...
Does anyone know what they really are? These are 3 pamphlets or possibly booklets. Are they a note pad? An instructions to something? Each one is a different shape and size. They're all from the early 1990s, but this is all the larger the photo is. You can see the edges so they are thicker than 1 sheet. They're not very large.

The first has a large square with "Sonic the Hedgehog" written in it, and the Sonic 1 winged ring. The 2nd is colorful, and has the 'very Japanese style" cutie art of finger waving Sonic off-kilter in the middle. The third is horizontal, Sonic 2 themed, and, for some reason it's pink. This photo is from a now-defunct collection site but the photo never had a caption, you were just supposed to know what they are. Of course, anyone can write in to clear up the mystery for credit.
