'First Edition'. Original plastic cylinder containing ten mixing and measuring 'sticks', 4 1/2 by 5 inch (box), printed label and illustrated advertising piece inside. Ingenious post prohibition cocktail mixing tool in which one would dip the stick into a glass and fill alcohol and mixers up to the appropriate lines. TA contemporary 1933 newspaper advertises the Mix-O-Meter for seventy five cents. This is an unusual variant, seen before with 8 1/2 by 1 inch box, this square box with advertising piece is a first for us. Very Good in Very Good box.
