Butter Thin Pancakes

This recipe is printed on a card from "Bun Boy", Barstow and Baker, California. The card is old and greasy -- which probably means my mom made these, though I don't remember them.

4 eggs
3 cups half and half
2-1/2 cups flour
3 Tbsp. sugar
3 tsp. baking powder
1 tsp. salt
1/2 lb. melted butter

Mix all ingredients except melted butter. Beat well. Stir in melted butter.
