lol i sell ltd. ed. art prints and number the backs of them and sign them, easy.
I'd say £25 sounds just fine JB, especially considering the amount of setup involved.... you could add a line explaining the slightly higher costs possibly.
Higher cost than what though?
Higher than another local tog who has the same massive pole with a camera on maybe, but if none, then no-one can have that same shot can they?
But do you only ever sell x number of the print, never to be sold again? Or is it purely a marketing gimmick?
