I do like this idea. Can Paste Ups be expanded to include printed media, or maybe have a category for that?
An example: New Urban Era in Tamworth have for the last few years been getting artists to decorate their bus shelters. Sometimes the artists have painted the bus shelters directly. Others have had specially cut boards painted at art festival events, and the boards were later mounted to a bus shelter.
However, one of the bus shelters (this one) was decorated with artwork painted by patients at a mental health centre. The artwork was printed onto panels, and it was those that were added to the shelter.
I made the decision to include that artwork as it was part of the series, and these pieces were not mass-produced. I did make it clear in the description how the art was presented (ie printed panels) so not to disappoint the unwary SAC visitor.
