“The Maas at Dordrecht”, a genuine painting by Aelbert Cuyp.
“What do we do now?” asked Harley. “How can we prove that the painting was painted in Holland in the 17th century by Cuyp?”
“There is a method now being developed,” said Dad, “that could give us that kind of information.”
“How does it work?” Martin asked.
Who Was the Artist?
“Do you know how criminals are caught by using fingerprints?” asked Dad.
“Sure we do,” said Martin. “Each person has a set of fingerprints that is different from anyone else’s.”
Harley spoke up. “Did the artist leave his fingerprints on the paintings?”
“Probably not,” said Dad. “Besides, they would have been wiped off long ago. Also, who knows what each artist’s fingerprints were like?”
