Ah, the mystery! Over 200 works by local artists are for sale — but you don’t know who they are. For the fourth year in a row, Louisville Visual Art is presenting the anonymous art sale “art[squared].” Each artist created an 8-inch square work to sell for $100 as a fundraiser for the LVA’s Children’s Fine Art Classes. This year the sale is Saturday, April 9 from 10 a.m.-1 p.m. But if you want to get in on the action prior to the sale for the general public, LVA is also hosting a preview party for $20 on Friday, April 8. Doors open at 7 p.m. with the sale at 7:30 p.m. Buy the work: Know the artist.
