Here is another one of my items highlighted in Bob Lemke's blog a few years back.

I still don't know it's exact origin, but now believe it's probably from the 1980's and has something to do with the Queensgate Mall in York, PA. It is made of thick plastic, not the same material of the English Chicken lids from 1976 & 1983.
Anyone with any info would be much appreciated. I've never seen another.
