Vintage Cowboy Hat Cereal Bowl and Cowboy Boot Mug

Vintage Cowboy Hat Cereal Bowl and Boot Mug. Know this was from the early 50's as I had lots of Cheerios and Boscoe out of them. Think it was given out as a premium from the grocery store we owned. Bowl is of heavy plastic with straw design. Measures approximately 9" x 7" x 2" deep.The mug has a design and spur on the back and is about 5" x 5 1/2". Shows use, but in very good condition..edges of bowl and mug are a little rough from use and there is some whiteness on edges from rubbing. Tried to show good pictures, but ask any questions
