So it seems the forgers have moved offline.
Wonderworld Comics in Taylor, MI was hit but, having read the Bleeding Cool coverage, refused them – but not before taking video images, and credit card information, which has been given to the police.
They claim to be from the west side of Michigan and theor story is that they got the sketches with certificate aof authenticity at Toronto comic con in person. They included the fake Robert Kirkman and Rob Guillory sketches we've already seen, more sketches purporting to be by Fiona Staples, and a few others too.
They may have hit six or more stores in the Detroit region, retailers are warned to be vigilant.
