Deletion of Berta Jayo

Comment: A  biography which previously included uncited detail about the subject's early school days, indicating primary knowledge. The Spanish Wikipedia has multiple deletions of articles on the subject as promotional: https://es.wikipedia.org/wiki/Berta_Jayo. Aside from the group show name-checks in the stack of references, the May 2007 El Diario exhibition review is relatively substantial, but neither these nor my searches are indicating that the subject meets the  or wider biographical notability criteria
