In the episode, “Tennessee Ernie Hangs On” (S3, 5/10/54), the Ricardos and the Mertzes join Ernie on Milikan’s Chicken-Mash Hour. Lucy plays a wooden and brass washboard.
Manufactured by the National Washboard Co., it is trademarked The Brass King. Lucy is playing the brass parts and we can see
that this side is labelled “Top Notch, Soap Saving Sanitary Front Drain, Do Not Rub Hard, The Board Will Do The Work! It appears that the prop department painted out the trademarked logo on the left, upper side.
