I bought these glasses at a family member's estate sales, but do not know much about them. They are dark blue with a raised white design of a girl, boy and a dog etc. on the outside. They are 4 3/4" high and have a 2" opening. There are no manufacturer marking that I can find. I believe they are from 50 - 70 years old. Years ago manufacturers of laundry soap, etc would include 'gifts' in the product cartons as an incentive to buy. I thought this might be one such item. I have a total of 8. I am trying to go with the idea of 'less is more', and downsize. I will either pass these along to my daughter/granddaughter if they want them, or possibly sell them. How do I find out what price I should ask for them?

Thank you. Jane

Sorry these are so large.
