One of the many unexpected delights in Prague was stepping down to Prague Castle grounds after an overwhelming hour around the castle buildings to discover a set of about a dozen photograph installations which were part of a Jiri Vsetecka retro called Prague Walker. All the photographs on display were brilliant and this one shot during May Day Parade, 1962 particularly so.
Any online pointers to this chap's pictures would be greatly appreciated. Thanks.
