Mystery Picture 091019

Do you know anything about this picture? Tell me!

I think this is Grandpa and ... is that Hazel? Does anyone recognize the location or the house in the background? I wonder what the occasion is for the fancy clothes and corsage?

UPDATE

Darrel Crawford writes in the comments:

The House looks likes the Duce home which is north of the Stutz home at the end of the block.

Thanks, Darrel! The following is the largest size image I have of the house, in case that helps.
