Why keep the French stubbornly insisting that these are Flemish?

Emeraude, from France, sells on 29 october a "Flemish School, 17th century" Annunciation, a small oil on copper estimated at 400 to 500 Euro.

It is the poor man's version of a work I discussed on my blog in June 2016; then it was also incorrectly described as Flemish. It was and remains a copy after Gentile da Fabriano, a purely Italian work. Considering the similarities in the two "French" versions, like the chair of the Virgin, some common origin (an engraving? A good copy after Da Fabriano?) may be postulated.

Value: not more than the estimate, surely, as it is a pretty poor painting.
