Is this a Muong textile?

Olivier Bizet (of Paris, France) has asked us this question from the tribaltextiles.info forum:

"Hello, I recently purchased a 6 ft by 3 ft weaving from a lady whose husband served in Laos in 1971. He reportedly bought this textile from the Muong minority when he was there. I have enclosed a link, I hope the pics will show up. My question is: does anyone know this type of weaving? Is there any information available about Muongs in Laos (perhaps she heard Hmong and understood Muong)? From the pics, can anyone tell me if it looks 30 years old? Thanks in advance, Olivier (Paris, France)"
