This is a one-of-a-kind set used in Dorchester Pennitentiary by notorious cult leader Roch Thériault.
It was used to make very few pastel paintings during his incarceration.
The box is from Weber Costello , Toronto Ont. and it’s complete !
12 clean Brilliant Colors + box + pastel tray is all there.
This was part of his property in Dorchester Prison. IT’s signed twice! Once on the outside left side of the box. Once on the inside tray cover.
Both signed Roch No. 242340B
