Help Architectural Artifacts (4325 N. Ravenswood Ave.) celebrate 25 years in the biz this weekend by bidding on an antique. Owner Stuart Grannen is holding a huge three-day auction Friday, Saturday, and Sunday. He has selected more than 1,600 antiques to put on the block (which you can bid on in-person, online, or over the phone).

The stock includes vintage chandeliers (such as this one, which once hung in the Chicago Civic Opera House), carved fireplaces, and more. And don’t worry: This isn’t only for the deep of pocket. Prices on some of the pieces start at just $5.
