The record reveals that the Owensboro Museum added an unannounced MASTERS OF PUBLIC ART, invitational exhibition running concurrently with the biennial. The commissions were selected from both groups,
I guess I fail to see what the issue is, if they selected commissions from BOTH groups
then no one lost out, it's not like someone entered this thing not knowing about the other event and that only ONE commission had been selected just from the unannounced event- leaving the participants in the first group out in the cold.
From what you describe there were two "winners", one in the first group and the other in the "unannounced" group event.
