Trish says that Manny stepped off a 16th century canvas by [Thomas] Gainsborough or [Anthony] van Dyck. Neither of those painters was a 16th century painter. Gainsborough was an 18th c. painter, and Van Dyck was a 17th c. painter. It's possible for Trish to have misspoken, but she is supposed to have a Ph.D, and be one of Christie's curators, as well as a board member of an art museum, and to be making Gloria jealous because she (Trish) is apparently perfect. This appears, then, to be an error on the part of the writers, who no doubt wanted to reference Gainsborough's The Blue Boy, and should have looked up the rest, but didn't.
