blue shield for people

This is one of the protective signs, probably the triplicated one is required in some areas.

The backside should have the text in the most appropriate language:

Protected by the Convention of The Hague, date 14 May1954, for the protection of cultural property in the event of an armed conflict.

After years of procrastination i managed to convince the talents from dieselch to do the gritty details for me, many thanks.
