This is a nice collectable glass mug from 1980. It is clear glass and has the Garfield characters in cartoon form.
I have two of these and this one has Garfield and Odie paddling a canoe with each one facing the opposite way. It has a balloon saying by Garfield "I'm easy to get along with when things gomy way".
It is signed by Jim Davis and has the McDonald's arch and dates on the bottom edge.
The mug measures 3" in diamter and 3 1/2" tall.
