i think the photo is mid 40's. i think the car is a clue but misleading because it is parked beside the house and overgrown. the spare wheel is on the right hand side of the car, and still rather narrow making me think its a late 20's early 30's model. it matches hair styles I've seen in my family photos from the 40's also with the slicked hair. but that also could be misleading. i think the suite style is your best bet along with the clothing style of the little boy on the bench might help.
