A signed Limited Edition print is a copy of an original piece of art that is printed in a limited number and will not be reproduced. The prints will be signed by the artist and the number of copies will always be shown on the print itself for example, 11/150. This means that this is a limited edition print, number 11 of 150. 

These are the first set of prints from the Limited Edition when the artist is checking the color and quality during the print process. Artist's Proofs are exactly the same in terms of how they are printed, the colors, quality of printing, paper etc. although there may be prints that are released as a special variant on different foil or paper stock. 

As there are fewer Artist's Proofs released they are more sought after and they come at a premium. Normally only 10-15% of the limited edition run is released as Artist's Proofs so, they are deemed as a valued collectible.

These prints will also be signed and numbered by the Artist just as a Limited Edition print but are designated with the mark A/P
