OSWOA's are works of art sized 4x6 or 6x4. They must fit into 4x6 photo album sleeves and they must be original works of art - not prints. If the work is digital art or a photograph, only one one copy can be considered a OSWOA. There are no limited or open edition OSWOA's.
If you are unsure of definitions for the other EBSQ galleries, they will be posted here. They will not be posted all at once but over a series of entries, so check this space often. If you need something before you see it here you can - as always, ask. Just drop a line to firstname.lastname@example.org.
