List of Sonic the Hedgehog clothing
From Sonic Retro
A few tips:
This is an advert from Metal Hammer magazine. Some time in 1993 - who knows.
Australian t-shirts from "Acme Merchandise". Going to hope that this wiki can still generate thumbnails for things on Retro CDN.
Promotional thing that came with the US 32X release of Virtua Fighter (and probably other games). Really should be able to get a full scan of this one.
