Finding Lost Architecture: Photo Submission

We are looking for old photographs of architecture and locations
in old cities, such as New York, Philadelphia, Boston, Chicago, San Fransisco, Los Angeles, Baltimore/DC or others (circa 1950s and before) for a new product!

We wanted to reach out to you, to help us uncover and honor the history of incredible architecture in our cities. We're looking for photos where you can tell us the approximate address. Please submit them below!
