It's a Bird, It's a Plane, Wait ... It's a Man on a WIRE?

This is a postcard in the local library collection, with no further information as to date, location, and why??  Based on the clothing of the men standing by the cart, I am guessing it was taken in the 1920s. Pole sitting was popular then, (see this link for more information on that) and I am wondering if this is not a variation on that theme.

Any information that would help us understand this photograph/postcard is welcomed!

The next question is: does anyone recognize this house as a Brookhaven home?  The hilliness from the street level to the porch area is interesting but makes me wonder if this is even from/about Brookhaven.
