ornate antique bubble glass picture frame w/1870s vintage wedding photo

Ornate Victorian era picture frame with domed convex 'bubble' glass over a hand-colored photograph portrait of a young couple (at the time of their marriage?) circa 1870s or early 1880s at our best guess. We have not taken this apart to examine the back of the photo, as it looks excellent just as it is.

This measures about 18 7/8" wide (side to side) and 12 7/8" high over the frame.

The gesso decoration of the frame has has wear and chipping, though overall not bad for a frame of this age. It's nice and clean, without fading, or staining from soot.
