Vintage RWP Wilton Pewter Mug Nolan's Fireside Inn, Corpus Christi Restaurant

This listing is for a vintage Wilton RWP pewter mug features one of Corpus Christi's oldest family restaurants from the 1950s. It is still open to this day, even making it through Covid!! Comes from a smoke-free home but I do have a dog and a cat (noted for those that might have allergies). Measures 4.5" H and the top opening is about 3 1/8" across from side to side. Has a blue ink stain on the inside. You may be able to remedy this with proper cleanser. I tried with a damp cloth and was able to get some out.
