Re: Gallery Show Question
Based on your comments it sounds like the association names were on the wall tags, not on after their actual signatures, like Karen indicated. I wouldn't worry about the gallery / show people adding your association membership information to your wall tags, though it might be better to have the tag say something like "PSA Associate Member" or "PSA Signature Member". Though not a pastel show, at the last OPA national show, every wall tag indicated the members status, Associate, Signature or Master.
Anyone signing as a signature or master member of a society when they are not one, is going to eventually get caught and might risk being expelled from the association for a period of time such as a year, which means they can't enter any shows. Plus it will make them look unethical to those buyers who understand signature status for memberships if/when they find out they aren't a signature member.
