The Northern Ohio Art Dealers Association will hold an expo of work from the finest galleries in the area this weekend at the Transformer Station. All of the art showcased will be available for purchase and should appeal to a wide range of taste, whether you’re an experienced collector or buying for the first time. A gala kicks off the expo tonight at 5, and the expo itself continues tomorrow and Sunday. Other events include a walk-and-talk with author Dr. Henry Adams and an open house with the Intermuseum Conservation Association. Tickets to the gala are $50 and include readmission throughout the weekend. General admission to the expo costs $10. (Gonzalez)
