hi,,,i have 2 SIGNED PROOFS, jimmy cauty stamps of mass destruction.1 1st class in blue,,,,1 2nd class in red.both are proof 3 from 4.both are framed and i have art republic invoices for both.i was just wondering if you guys think they are a good investment as i have no idea what sort of prices they may fetch in the future,i kinda beleive that cauty could be the next warhole,wel see eh.anyway any feedback would be helpful,and if any1 is interested i may sell at the right price.if you know your stuff im sure you realise that these peices of art are very rare ,less than 26 were ever sold before the royal mail made art republic stop selling or producing them,if any1 out there has a 3rd class print i would be interested in talking to you,and happy to talk to any1 about these contraversial images.thx,,,,,,,,fishypie.
