I bought this window for $15.00 from a window company which had just replaced the original windows in a house built in the 1950′s, in northwest Phoenix.
I bought an antique “wedding book” from Goodwill (just like a baby book but to document a wedding, not a baby). I took some of the pages out and attached them to the window. The wedding book had information in it regarding the couple who originally used it when they were wed in Michigan in March of 1919. That information is still visible on the back side of the window.
