When Edward Marlo’s Unexpected Card Book first appeared in 1974, it received mixed reactions. Though it contained a huge selection of varied material, it was unfortunately riddled with enough errors and missing information to make learning the material a daunting task.

But all of that has now changed. Bob Nelson, after tirelessly and unselfishly devoting two years, has completely rewritten Marlo’s original text and the result is this newly revitalized volume filled with some of Edward Marlo’s richest and most diverse private works.
