Vintage Strawberry Mugs Milk Glass Anchor Hocking Fire King USA. This is a set of two darling, vintage coffee mugs. They have a strawberry motif and are marked on the bottom. They are made from milk class by Anchor Hocking for their Fire King line in the USA. they are a little rough around the top edge in some places. I believe this is from the manufacturing process and is not actual damage, but I did pointed out in the pictures. There are no other chips or cracks. There are multiple sets of these cups for sale, but these pictures stand to represent all of them. Please see the pictures for the full description.
