For your consideration, I have a Vintage St Clair Glass Ashtray Large Red Bob & Maude Elwood IN.  This is in good condition with no chips or cracks.  There is an imperfection on one of the cigarette rests but it looks like it was done at the factory - see last picture.  It is 5" diameter. This comes from a smoke free home.  I will be listing several vintage items so check out my other listings as I will combine shipping on multiple sales.
