Mug, Coffee

One souvenir coffee mug from Bob-Lo Island. The mug is made of opaque white glass. It has a curved handle with a thumb rest at the top, straight sides, and a short base that is slightly smaller in diameter than the mug. The sides are stamped with a blue drawing that depicts an image of the Detroit city skyline, bow views of the steamships, STE. CLAIRE and COLUMBIA, and a "Bob-Lo" life ring with a caricature of Captain Bob-Lo at the center. Large blue text over the drawing reads "Bob-Lo." A raised shield emblem on the underside of the mug shows the letter, "F" [Federal Glass Company], at the center, and adjacent raised text reads "Heat Proof, USA, 25."
