Thanks to Darryl for sending the photo! He explains:
A hidden history is revealed at 16th and Trenton. We’ve heard stories from long time residents that this house on the corner used to be a neighborhood grocery store, but have never seen pictures from that period. Today, as the house is undergoing another transformation, I caught this cool image that confirms the story. Kind of neat!
UPDATE: Thanks to everyone who’s added to this story via the comments – don’t skip them!
