why the contents are written in these strange languages i've never seen something like that before!!
The word "contents" in different languages started to be printed on the front of the boxes in the 1980s. The practice ended in the mid-1990s, probably 1995, although boxes produced before this date and with the printing on could be on sale long after the practice stopped.
I've attached a scan of the 3456 ambulance box which went out of production in 1994.
