Me with one of the artists, the promotion of which I am now starting to deal with, it was decided to manufacture replicable copies of three of his paintings before the upcoming exhibition. How to sign (on top of an existing signature on the reverse side, a marker or butter) and label (number of copies) limited edition prints? Can the size of prints vary slightly from the originals?
At what other points in the manufacture of lottery products is worth paying attention to?

On these copies behind write legibly and indelibly, that - is a copy made such and such a way with the original picture. And then all the details originala.Ukazhite number of copies made (of course, the smaller the better < ! - ~ 1 ~ - "). "Certify" and the signature hudozhnika.Nekotorye make more certificates. It is beautiful and adds solidity
