This site as mentioned by Jonathan is an excellent showcase of Herb Lubalin's work. Herb and Lou Dorfsman were great friends and often worked together. In further musing concerning the origin of Dofsman's 'Ha Ha Ha' lettering, from looking at Herb's sketch work, I think it's further proof that type was often hand rendered from sketches. It just seems to be too perfect not to be hand crafted. Herb used the same similarly fine fonts in his work and could well have had a hand in 'Ha ha ha'. And since we're on Herb's work, here are two other great things of his.
