I don't remember this from 1991 to be honest, which is strange because that's around the time when I remember pretty much anything involving comics, music and useless information. Interestingly this is also the time of my degree finals. I remember almost nothing from them.
It's a scan of the Neil Gaiman written Teenage Mutant Something Turtles (remember the farce over using ninja or action on British TV?). A very young looking Lenny Henry and Jonathan Ross in there as well.
Neil talks about it here on his blog FAQ.
No credit for the artist but based on the time, who Gaiman was working with and the list of artists on the wiki page - I'm guessing it's Mark Buckingham. Anyone care to confirm?
