Automotive Limited Edition Print

What is the difference between a poster and a limited edition print?

Limited edition prints are printed in a short number of copies (an average of 300/350 copies for each painting). Every has a specific number ans signature, below, on the right side. Usually my prints are edited with the pilot's portrait in black and white, under the colour picture of the painting. It give a kind of "vintage touch". You can consider this limited edition prints as collectibles: each model is avalaible for mostly 3 years depending on its success. When the print is sold out, it is never edited again.
