Check out this old map of Del Ray north of Alexandria from back in 1921. It’s amazing to see how undeveloped the area was. The yellow structures are wood frame buildings and the pink ones are brick.
Here’s a map of the same area today.[googlemaps https://maps.google.com/maps?f=q&source=s_q&hl=en&geocode=&q=Del+Ray,+Alexandria,+VA&aq=0&oq=del+ray,&sll=38.804835,-77.046905&sspn=0.024246,0.040941&gl=us&ie=UTF8&hq=&hnear=Alexandria,+Virginia&ll=38.804835,-77.046921&spn=0.011384,0.020471&t=m&z=14&output=embed]
