The Land of Loony Logos, first explored in the May 1971 Word Ways, was revisited and the following items were unearthed. My thanks to Dave Silverman and R. Robinson Rowe for several of the looniest logos of this group. The final six should be printed in color (as specified by the instructions in parentheses).
