I found another french jokes-gadgets-gizmos-novelties catalogue. It was published by the Société Le Record du Rire (The Laughter Record Company), Paris. This publication dates of 1929, that is just one year before the catalogue of the Société de la Gaîté française. It offers the same kind of funny and magical items, and also some small musical instruments.
I was very glad to find, page 137, another advertisement for the Ocariflûte, with another drawing. The brand name is not mentionned but the instrument is very recognizable, with its square heel. Here, the nose flute is called La Flûte nasale magique (The Magic Nasal Flute) and is supposedly "patented in every country"...
The text says:
(patented in every country)
THE MAGIC NASAL FLUTE
anyone can play it
with no musical knowledge
The Magic Nasal Flute is an instrument really new, totally different from the others. It is entirely made of metal and weighs only a few grams. Thus, one can always have it in the pocket. Once placed as specified in the user manual provided with each instrument, only a few minutes are necessary to learn to play it. Any tone is obtained. No fingering. No need to hold the instrument.
It is capable to produce delightful modulations and any popular or classical melodies (opera, ditties, etc.)
Any animal scream imitation, and particularly birds ones (nightingale and canary) are perfectly reproduced very conveniently.
As a result of a special agreement with the manufacturer of this marvelous instrument, we provide it complete with a detailed user manual at ultra-reduced price of 3.50 Francs.
Anyone can take benefit of this precious, useful, agreeable device as well at home as in society.
