These special thangkas were not painted. They were embroidered with colored silk. Embroideries with Tibetan Buddhist subject matter were executed in the far eastern part of Tibet and China. Thewy are very rare.
This first thangka was embroidered [Tib.:»tshen drub ma«]. It shows the god of wealth »Vaisravana« [also called »Kubera«]. It is very old - 14th century.
The other two examples for the thangka categories are not old. The first of the two shows Samantabbhadra *] with appliqued beads and the last example two Citipati skelletons.
