These coasters were used by Sambo's Restaurants for the bicentennial year. They are a colorful red, white and blue and are in fairly good condition for something so old. They are a little discolored due to age and probably because they were used. In the bicentennial year many companies had a little patriotic campaign going on and Sambo's was no exception. They are about 3 1/8 inches across. They have been in a smoke free environment. Pennsylvania Sales Tax at the rate of 6% will be collected at checkout. Thanks for stopping by!
