As far as rad and unexpected Christmas presents go, it doesn’t get better than this gift I received from my (amazing) wife this year.
According to this video, the pins were given to anyone who played Sonic 2 at the 1992 Future Entertainment Show in Earls Court London. The pins are well-made and full of early-90s Sonic charm.
I absolutely love these! If anyone knows anything else about the origin or distribution of this set, let me know!
