THank you so much! 

I'm new here and I need some help. 

Does anyone recognize this building (sorry, I can't get a better picture)?  It stood at the corner of Main at Lamar, across Lamar from the Lamar Hotel/Metropolitan Theater (which you can see in the background).  I could swear I've seen pictures of it before but now that I need them, I can't find any.  I might have conflated it with another building but the Moorish detail over the door is so distinctive that I don't think so. 

The picture was taken no later than 1934--Douglas Fairbanks' name is on the theater marquee in the full print, and his last movie came out in 1934.  The cars in the image are all pre-1935, too (no shield grilles).

Edit: Looks like it could either be 509 Main Street or 407 Main Street.
