An edition of a print includes all the impressions published at the same time or as part of the same publishing event. A first edition print is one that was issued with the first published group of impressions. First edition prints are sometimes pre-dated by a proof edition. Editions of a print should be distinguished from states of a print. There can be several states of a print from the same edition, and there can be several editions of a print all with the same state. For limited editions, cf. below.
