Plus, sealing wax is designed melt at a rather low temperature and would not be very durable for that reason.
So I'm thinking along the lines of cheap, easy to obtain polymer that will carve easily and be durable. And in the 1980s there would have been a number of polymers that would work - some type of polyethylene is just guess on my part.
