Hi Camitchel,"If anyone can point me to a scholarly analysis of mid 20th century American frescos I would very appreciative!"
Such analysis does not exist neither ANY analysis of American fresco, but very much needed!
It would be wonderful if you create one.
"Has anyone ever heard of these frescos outside of Maine????"
