When the printing press was was invented in the 15th century, woodcuts were used to add illustrations to the text. The choice of process depends on the preference of the artist and the suitability of the image to be printed to the process selected. As the name indicates, these are unnumbered and unlimited copies of an image. They may be signed or unsigned. More than one edition of the same image can be run.
Posters are an example of unlimited editions.
Posters can be displayed either framed or unframed and are the logical choice for many settings such as dorms, rental units, offices, temporary facilities, or other settings that would benefit from a tasteful and personal touch at minimal expense. Insula Verde plans to add additional images to its existing selection of posters.
