The National Sandwich Idea contest was held between 1956 and 1981. It was sponsored by the Wheat Flour Institute. Each year 20 sandwich recipes, created by Food Service professionals, were chosen as the top sandwich recipes from hundreds of entries.

The Guacamole Open Club Sandwich was the number #1 recipe chosen in 1964.

It was created by Viola English of Dayton, OH.

The Guacamole Open Club Sandwich is a delicious concoction in which the
avocado mixture (Guacamole) is served over the bacon and lettuce sandwich,
open face, on Russian rye bread.
