So what makes this different? This one is broken!
In season 1 they were plaster, and the process to make them involved putting the “heroin” drug bags inside the plaster in the mould. This meant some of the bags stuck into the plaster. The season 2 Mary’s were made of a thin plastic and moulded again. The paint job was very similar to season 1 but they didn’t flake paint as easily….and finally the season 3 Mary’s were an even thinner plastic and had a more dark paint job…more weathered not with mud and earth but with the paint itself.
