As you may or may not know the encased gentleman, Dorje Drakden (rDo rje Drag ldan) takes alcoholic offerings, and Tibetans are happy to give it to him - in barrels.
This is my clumsy attempt to show that the two bodhisattvas in the back (my guess from this distance would be Avalokiteśvara and Mañjuśrī) are not too happy about all this alcohol flowing freely and hence they are blindfolded. Specialists of Nepal could tell you that this practice is observed there as well.
