We mentioned this earlier, but thought it probably deserved its own entry.
Boom! published Over The Garden Wall, a comic book adaptation of the Cartoon Network show . We highlighted it when solicited, but o its publication it seems to have sold out in seconds and rocketed in value.
Nevertheless, it is quite possible that some comic stores in philistine areas may still have copies at cover price.
They are also even more likely to have Adventure Time #33 which contained a preview of the comic book and has sold for up to $11.
And $2 until people realised.
Of course the real money if for the press kit with screener and vinyl record… over $200!
