The mugs are heavy and remind me of Fire King although these cups are not marked. The antique car motif makes them a little more masculine looking. The red car is a 1903 Ford, the Yellow is a 1910 Buick and the White is a 1907 Rolls Royce. The Rolls Royce has a small imperfection where the decal may not have been applied correctly at the factory. We must collect 6% Pennsylvania Sales and Use Tax at checkout. Thanks for stopping by!
