This Victorian-era postcard was made at a photography studio or perhaps by a traveling photographer using a wishing well prop set. Photographers usually also supplied working class men with suits, as appears to be the case in this quaint souvenir photo postcard.
It is in good condition though the lower left corner is bumped (see photos). Although it is unsent and not postmarked, it has this inscription (in tiny cursive) on the back: "What do you know about this Jim Denun (?), Roland Sweetman and I. We look like we had been drunk for a week although we hadn't been." And it appears to be signed "Lee."
It is 3 3/8" by 5 3/8".
