Deletion of Arnaud Courlet de Vregille

Comment: per  #4.b "has been a substantial part of a significant exhibition". The exhibitions are listed in the French Wikipediahttps://fr.wikipedia.org/wiki/Arnaud_Courlet_de_Vregille some verifiable through catalogs (primary but suitable for verification purposes on something like this). Most of this artist's career happened before material was regularly put online so it would require access to offline french sources which I don't believe anyone at AfD will be able to provide. Based on the available evidence we do have, and assuming good faith the French Wikipedia information is not an outright lie (see no evidence for it) I think it would do more harm than good to delete this artist
