Vintage Chinese thermos flask with a picture of best 1950's 1960's children's party

Unusual vintage thermos flask with an image of 1950's or 1960's kids party. The flask is most likely Chinese origin as it has the same type of aluminium lid/cup and handle as the Chinese floral thermal flasks have. This thermos has never been used - it has only been on display. The lid/cup has a couple of dents (please see the eight photo). The stopper is covered with cotton jersey. The height of the thermos is 25.8 centimetres. best
