The term ‘Limited Edition’ indicates that the image can only be reproduced up to a specified number of times that is stated on the print. Each print is signed by the artist and tells you the number of the print within the edition. So 2/50 written on the left bottom corner of the print tells you that that is the second print in an edition of 50 prints.
It has to be noted that one print edition refers to prints of a certain size. Therefore another print edition of the same image can be produced provided that the size is significantly different without violating the term ‘limited’.
