This 1950s recipe from Borden didn't come with an image of the pie. But it did have this snazzy illustration of Bessie Elsie.
Here's Bessie's recipe for Magic Pumpkin Pie.
1 (9-in.) pastry shell, unbaked
2 cups canned pumpkin
1 1/3 cups (15-oz. can) Eagle Brand Sweetened Condensed Milk
1 egg, unbeaten
1/2 tsp. salt
3/4 tsp. cinnamon
1/2 tsp. nutmeg
1/2 tsp. ginger
1. Combine pumpkin, Eagle Brand Sweetened Condensed Milk, egg, salt and spices; blend until smooth. Pour mixture into unbaked pastry shell. 2. Bake in moderate oven (375˚F) 50 to 55 minutes or until knife inserted near center comes out clean.
