Rudimentary Skull cutouts 2

I worked at a Plastic ThermoForming  company on and off in upstate NY for a few years and the second best take-away from there was a bunch of these 1/4" high plates, 1/8th" thick black cut-outs, in the basic shape of a skull.

I scarfed up a very small load of them then.

I painted white acrylic on them back in 2005 or 2006.
I still have them and here is the 2nd of them.  This the "outside of the plate painting"
Not showing the "haircell" texture.  and more prone to scratches through the years.
