From Life magazine, 1943, the writer seems undecided as to the validity of collage, calling Vail 'a real master' of a medium he appears to dismiss. Collage is 'quietly threatening to become a fad'? Ha-ha - tell Picasso! What a fool. '43 was was too soon after the event to recognise Dada as a key artistic movement rather than 'another harmless little hoax', perhaps, although I doubt that the idiot would acknowledge that if he were alive today.
Laurence Vail had a famous wife in Peggy Guggenheim, as well as knowing Man Ray and Marcel Duchamp in Paris, where he was known as 'the king of bohemians', no less.
