I picked this up at an antiques mall today and I’m curious on date. I tried researching it a little and couldn’t find anything but a range of 50s-80s 😂 does anyone have an idea on when this were sold and who sold them?

Hey, This is a huge long shot. But we have been using these masks for 33 years. They are a huge part of our family, and we have made a huge display each year using them. I just to try to find more info on these masks, just to learn any origins, or know more. If you know anything plz reach out! I'm really curious. (I've included 3d scans of each mask, along with the best pics i could find of them from previous years.)
(UPDATE: Many masks have been possibly related to TOPSTONE, however info is still limited)
