The first image shows Main street looking south from just north of 6th in 1918 and as it looks today. The second image is looking east at the Burbank Theater from the west side of Main.

As you can tell, the theater was remodelled with a deco look at some point and by the time this photo was taken had turned into a 'Burlesk' house.
