Whimsical Windows - Labor Day movement mystery

Toby's fun meme Whimsical Windows/Delirious Doors is back the day before Labor Day in the US and Canada (Labour Day?) and windows are peripheral to the scene which is a mystery to me. So I guess that this pic of my day amidst a labor type event in Steubenville in 1938 with my father, aged nine. Dad looks winsome as that man in white looks irritated withe my photographer grandfather (I assume the guy kept walking...). Of course in front of the building's windows and doors is a labor demonstration of a sort with the FDR era NLRB (National Labor Relations Board) signs displayed. Who was Clyde Armstrong and why the demonstration on a hot Summer day? These are myriad mysteries - however I enjoy the look back at this long ago event...

Shadow Shot Sunday - Mesa mystery

Three well-dressed gentlemen in front of a mesa in the Grand Canyon State, (1937?)

License plate mystery solved?

 Shadow Shot Sunday 2 and my namesake grandfather - it's not necessarily new for me as I have been chronicling the distant family past for awhile now (as Patti knows :). Yet my father's sole sibling, Aunt Terry has been following these photo memes and sent me another box of old photos a couple of weeks ago full of photos I haven't yet seen...
Always interesting is not knowing the background of the shot at all - so I merely guess. 

The three gentlemen, Grandpa in the middle, are obviously on the way to someplace special since they are wearing nicely tailored suits - in the desert? Maybe this is on U.S. 60 west from New Mexico?

More interesting are the two license plats on the car. his usual Ohio 'RV' plate and another - his radio license? The second photo, taken in 1977 or 1978, may explain that - the 1937 Ohio tag and...the 1937 radio license? I cannot say - however, along with the shadows, I do like a mystery...
