In the 1956  I Love Lucy episode The Ricardos Visit Cuba, Little Ricky is seen reading a 1951 Golden Book entitled “The Great Big Car and Truck”. It is a larger size than the Little Golden Books and measures about 12 3/4″ by 9 5/8″. The copy I see on eBay pictured here is a twelfth printing from 1951 with art work by Richard Scarry.
