Southold Historical Museum is inviting artists to participate in its Ten-Squared online art exhibit and sale this summer. The theme for this non-juried exhibition is ‘At the Seaside’. Artists are allowed to submit up to three pieces of work, each measuring 10” x 10”. The artwork will be sold for $100, with half of the proceeds benefiting Southold Historical Museum and the remaining half going to the artist. Finished works are due with submission forms at the museum from June 2 to June 6, between 10 a.m. and 2 p.m. The museum is accepting all mediums and there is a limit of three submissions per artist. The online exhibit and sale will run from July 1 to Aug. 31. For artist inquiries, please email art@southoldhistorical.org or call 631-765-5500.
