Original (orig)
An original painting or drawing from which prints are produced.

Open Edition
A batch of identical prints with no limit on the number that may be produced. If the publisher runs out of an open edition they will just print more. Some open editions are signed by the artist, but in many cases they are not.

Limited Edition
A batch of identical prints, limited to a given number of copies. For instance, a limited edition of 500 simply means that only five hundred copies of the print will ever be produced. Each print in a limited edition is signed by the artist and individually numbered.

Artist's Proof
Essentially identical to the description above, except the edition size is generally no more than 10% of the regular limited edition. Occasionally an artist proof will bear an extra signature or two, but in the vast majority of cases the only difference between the regular limited edition and an artist's proof is the serial number and price.

Publisher's Proof
Just about the same thing as an artist's proof, although it is slightly more common for a publisher's proof to be issued with additional signatures, and /or companion prints. This is by no means universal, many publishers proofs are no different from an artist proof or a limited edition except for serial number and price.

Presentation Copy
Essentially identical to the limited edition (including all signatures), but lack a serial number and certificate of authenticity. They are usually presented to the aircrew who have signed the print.

Remarque (rmq)
An original drawing, drawn directly onto a print. In most cases these drawings appear just beneath the image area of a print, in the signature border.

Giclée is a French word meaning, "a spraying of pigments" (pronounced "zhee-clay"). In terms of art work, a giclée is a piece that has been produced using bubble jet printing technology, although the printers used for this are of a much higher grade than the normal home computer version, and produce superior image quality when compared to lithographs. Giclées are most commonly offered on canvas, or on water colour paper.

Secondary Market
When all copies of a print have been sold, the only way to obtain a copy is to purchase it from a collector who is offering one for sale, or from a dealer who has bought one from a collector, these transactions are termed 'secondary market'. Almost invariably, secondary market prints are sold at a higher price than the original issue price, in some cases many times higher.

Sold Out
This simply means that all available copies of the particular print edition have been sold.
