Works are signed, dated and numbered but are limited to a set number in this case seven prints. That is not to say that seven have been produced.
Signed and numbered series
Works are signed, dated and numbered as they are produced. The artist keeps a record of the number of prints produced. Often there will only be a small number of prints made so to have one of only three may be better.
In both cases if a single image in this exhibition has a red dot another print will be available so please ask.
