Note by RWF:

The postcard is mailed, like the view shown, from the Ontario side of the Niagara River. Whether the brothers drove around via a bridge (likely), took the cable car (perhaps a luxury for young men during the Depression), swam (doubtful — my father couldn't swim), or went over Niagara Falls in a barrel (traditional, but doubtful), I do not know.
