The Aspen Thrift Shop’s artwork is prepared for the art sale at the Red Brick Center for the Arts in Aspen on Thursday, July 22, 2021. The sale is a culmination of two years of artwork and will be held from 10 a.m. to 2 p.m. Saturday with a preview from 4-6 p.m. Friday. The sale has signed art and quirky finds, some of which will be sold in a silent auction. (Kelsey Brunner/The Aspen Times) Less than 48 hours before the Aspen Thrift Shop’s annual art sale, organizer Katherine Sand was still coming to terms with just how many posters, books, paintings and ephemera she had to sort through and price.
