I know my guitar was made by Manuel Contreras, because I spent an afternoon in his workshop discussing construction details and other things with him. It is true that he mostly made classical guitars and personally made very few flamencos. He told me that most of the flamenco guitars sold at his Calle de la Cruz and Calle Mayor, 80 (Madrid) shops with Contreras labels were student models made by outside makers.
He personally signed "Manuel G. Contreras" diagonally across the labels put on the highest-quality guitars that he made. His lower-quality guitars have the same labels without his signature.
