237 Powers Street
Re-Brooklyn has a then and now comparison of 237 Powers Street. According to the caption on the original photo (which came from the NY Public Library), the house was built in 1855. If that's the case, we'd wager that the entry hood (and flagpole above) were a later addition. As you can see at Re-Brooklyn, the house doesn't look anything like this today, though what you see in the 1923 photo is probably somewhere underneath the lovely vinyl job.
