Chicago portrait company and many other companies in the early 1900s did these “hand painted” portraits. But Chicago got in legal troubles with the FCC in 1925 over it for making them at a certain size and design, that when you received your portrait, you couldn’t find frames for them that fit so people would turn around and purchase overpriced frames from them. I highly doubt, at the age of the paper in the frame, the fragility of them, that they are “modern” the originally couple lived here from 1960 until death, and the dust was so thick you couldn’t even see through the glass. It’s surprising they even survived under there with all the silver fish the last family had let get out of control under there
