One of a series of picture postcards published shortly after WW2 in the Netherlands. It shows a Sherman Hybrid IC of the Canadian Army and is captioned "Demonstration of allied weapons". This is likely "Commodore" shown above.
Mr Carel Kramer (1883-1957) made this photo in Rotterdam, during one of many demonstrations by the Canadian Army during May - September 1945, to show the men & machines that had brought peace to the small country. It was part of the activities which helped to forge the everlasting bond between the Canadian and Dutch people.
