The final image shows a strip map at Gallery Place. WMATA tends to test out new signage at Gallery Place, and this is the only place on the Red Line where the strip map includes arrows showing the direction of travel. 10 got this one right.

Thanks to Ben Schumin, DC Transit Nerd, and Sand Box John for submitting photos! Thanks to all of you for playing.

Next Monday, we’ll have 5 more photos for you to identify.
