Advertising card from Chocolat Poulain
The card show a number of sailors. One with a sextant, one with a map and two who seem to be smoking. The last two are a bit unclear and do not seem related to the overall theme. The company Poulain still exists and was founded in 1848. Looking at the card and the text (font) it probably originates somewhere from the early 20th century (maybe 1920s?).
