I would examine a few of these portraits to make sure they were
"paintings." Melvin Ruggles, (JAIC 1985, Volume 24, Number 2,
Article 4 pp. 92 to 103) described a number of photographic images
on canvas that were later painted over. This is only one
possibility, but transmitted light examination, UV and IR as well as
microscopic survey of about 30X could tell you a lot about the
structure of the objects you are looking at.
