Weenenk & Snel, Den Haag

The example card just has a logo but other cards have this plus the name as above. Other cards (eg 1922) have a logo which is the names in a circle. By 1966 the location is Baarn.

The example is illustrated by Freddie Langeler 1899-1948 (I have seen sightly diffierent dates), a female artist based in Amsterdam who illustrated a number of books for children.
