Saturday Leftover Day.
Found this in the online archives of a Dutch newspaper. I am in the process of finding out what it is, but here is what I have now. The strip ran from October 18 1960 (a tuesday) until April 18 1961. It was signed Droc and the copyright belongs to ABC Press, which was a photo syndicate in Amsterdam. The owner of that syndicate was a Hungarian refugee who had started the bussiness in 1939. So I am not sure if this is by a Dutch artist or bought abroad. The characters and concept are the same as Peanuts, but diferent. There seem to be quite a few 'feminist' gags, with the girl character talking about coming the president. Which is odd, because we as a country were (and still are) a monarchy.
