We don't think Buster has adorned or advertised a soap product since he did the take-off on Barbara Feldon in a bubble bath, but here is one he'd probably like.
Busterís Bay Rum Soap for discriminating gentlemen and ladies is reminiscent of a by-gone era. Made with all natural ingredients by the silent film buffs at Cats in the Cradle in Alton, New Hampshire, with the same dedication to their craft that Buster Keaton had for his.
Not only for bathing, this soap has a great clove fragrance that is perfect for freshening up a drawer! Produced by permission, Douris Corporation
