Salem North Star Ashtrays

I don't smoke (6 collapsed lungs in my late teens early 20s), nor do I allow it in the house, but these are some of my favorite things that I own and the first post of something really rare. I have only seen these for sale two other times besides the ones I bought. The larger one is 7 1/4" x 7 1/4" and is marked "Ovenproof". The smaller 3 are 5 1/4" x 5 1/4" and marked "ovenproof 62". They could have been a cooler shape compared to all the other great ashtrays of the 50's and 60's but they are still some of my favorite pieces.
