I'm not an expert in art, but I have more and more flair and knowledge with the time.
I also think that William Hodges was a generic name for mass-produced work of art. A lot of these ''period/style'' painting were mass produced and if someone has a good link to learn more about how these were done, let me know...
Lastly, since we can see from the replies on this forum, that these painting are widespread over the US; and considering that no museum/institution has information on the painter, the explanation could be the ''mass production painting''
Anyway, theres a link with some information on a william Hodges, but style just dont fit
