I’ve seen ‘galleries’ all over. How does one know if it’s really a fine art gallery or not? I have a pretty good eye as I’m a novice painter with a few years of old-style academic training under my belt (casts, nude models, etc). All I know of that I’d call mostly respectable are Maxwell-Alexander and Arcadia Contemporary. But they deal only in living painters.
Honestly it’s about what other galleries think of them
The key term here is provenance, how strong and reliable is proving the history of ownership if that gallery is involved, can they produce the prior provenance on demand
I don’t know the best way to find that out from the outside. If you try to sell a piece you own you’ll find it very quickly, after you mention where you got it from
