It's a new way for contemporary artists to show their work at a large scale using custom printed wallpaper. One of the main reasons for this development is the affordability of a one-off custom print. From exhibitions in private galleries to local art centres and museums, large format prints on wallpaper material can now be seen in a new light - as another way to express the artist's concept. Have a look at these examples:
