Don't miss the fanciful, thoroughly enjoyable exhibition "Curator's Choice: Celebrating 40 Years of Concept Art Gallery," at 1031 S. Braddock Ave., Regent Square, only through Sunday. It comprises two floors of work by almost 60 artists selected by 23 art professionals, ranging from 19th-century, gilded-frame finery to a contemporary suspended space station, most for sale. Among choice picks, critic and curator Graham Shearing has produced a visually ticklish melange of pluck and elegance patterned on historic Cabinets of Curiosities. Snatch up a copy of his limited-edition catalog cum artist book, "Signs and Wonders: A Modern Wunderkammer" ($25), vintage Shearing (who else uses words like huggermugger?). Hours are 10 a.m. to 5:30 p.m. today through Saturday, noon to 4 p.m. Sunday. Admission is free. 412-242-9200.
