Deletion of Marc Y. Chenevert

Comment: He donated his work to the National Museum of Commercial Aviation and this counts under  #4D "represented within the permanent collections of several notable galleries or museums". The problem is the word "several" as the National museum is just one. However the source also says "All of Marc’s aviation artwork is included in this gift to the Museum with the exception of his Braniff International Airways drawings (which he plans to donate to a group in Dallas, Texas). This group is currently working towards a Braniff International Museum that will be exclusive to historical Braniff memorabilia, art and artifacts, including artworks by the renowned Alexander Calder as well as those of Marc Y. Chenevert." So if you count this second non-existent museum it would be "several". Another problem is the complete lack of sourcing for , nobody has written about Chenevert anywhere (in reliable secondary sources). My guess is this artist will become better known now that donated artwork where it can be exhibited and written about, but it will take some time to see if that happens, so
