I LOVE subway art! I switch the signs out of a frame in my dining room every Holiday! They look so cute and festive.
Here's the trick...Save the "Art" to your computer, send it to Sam's Club/Costco Photo Lab, and order it in a Poster Size. It's less that $6 for a 18x20! Easy and cheap way to decorate!
Just an example of the frame I change out in my dining room! Yes, it still has the Christmas Subway Art in it. Will be putting the V-Day Art in next!! :)
