I found this the other week and just assumed it was Chance because it was sat with a couple of swirl pattern dishes.
But now I'm thinking there is a chance that it is not Chance.
Okay, I looked on Chanceglass.net and these pages first finding nothing similar.
helpful IDing info:
it's shown against a piece of white A4 paper for reference of size and colour.
it's printed both sides.
colours are clear glass, yellow and orange/red design with a gold rim.
