This is a marvellous set of 10 poster stamps edited by Swiss firm Nestlé-Peter-Cailler-Kohler Chocolate. The set belongs to the series Nature and its Secrets edited in the middle 1950s and represents series n. 50 which theme is about Parents’ love in Animal Kingdom.
The collection is complete which add to the extreme difficulty of having all of them stay together after all this time. The stamps are made of thin paper with dimension 2.28 x 3.14 inches for the big ones and 1.6 x 2.2 inches for the others with text in French, German and Italian on the rear.
The stamps are brand new as they still have their coating glue unused.
This article is in good conditions as illustrated in the picture shown.
