I'm sure buyers would want to know more information like what material it's made of and what is it coated with. Also in which year was it manufactured.
It looks like some paper mask , and at that price , doesn't feel like something that rare and interesting
It's a plastic mask the company produced these masks in the 70's, do a google search and you'll almost find nothing about it.
These are somewhat undiscovered masks from césar.
I'm just placing this tread on here to see what it will go
That's all
