The Wheaton Grand Theater (or just the Grand) opened in 1925, with one screen and 1,000 seats. It first closed in the late 90's as a second run theater, but new owners re-opened and ran classic films, concerts, and other shows until 2006. The Grand has sat empty since, although a new owner is in the process of renovating and hopes to re-open in 2014.
I think this sign has been lightly refurbished in the last year or so-the paint looks nice and bright, even though the glass is mostly broken and missing. I hope the restoration of this cool old theater is successful-the exterior is still in nice shape and has lots of great period detail. It should look great.
