Thangka - tangka - thanka - tanka painting

A painted, embroidered or blockprinted Buddhist banner, hung at family altars or monasteries and sometimes carried in religious processions by Buddhist monks. The word "thang" means flat in the Tibetan language; hence the reference is to paintings done on flat surfaces. Thangka paintings can also be rolled up as scrolls, and are popular among traveling monks. Source: http://en.wikipedia.org/wiki/Thangka
