Island Archives is keen for more people to see its collection of material linked to the German's photo ID system.
The coloured German photo ID cards are a stark reminder of occupation and all adults in Guernsey had to have one.
By October 1940 the Germans ordered that people register and carry cards that identified them.
Archivist Vikki Hart says this followed a series of British commando raids on Guernsey in the early days of the occupation:
"The Germans were concerned about British soldiers that might be hiding, so they asked everybody to register, so they could check details on the streets with the identity cards."
Archive assistant Caitlyn Le Patourel says that by 1941 an order went out that everyone had to carry new cards with a photo of the holder:
"You just couldn't confirm identities properly by just putting hair and eye colour. That's why they wanted those photographs so you truly had your face, name, address, everything, when they asked for it."
Caitlyn says this was the inspiration for the display of a parish douzaine office, where the cards were put together:
"It's like the clerks have just stepped out of the room. They've got their pens and pencils out and the music playing on the radio because radios weren't banned until 1942. They've got the map of St Peter Port out and it's a really good insight back into 1941 and the work of the clerks and constables."
The Island Archives at the Mignot Plateau are open daily and the display is free. Extra or extended opening times have been organised as follows:
Thursday 29 May 0930 - 6.30pm.
Thursday 12 June 0930 - 6.30pm.
Saturday 21 June 11 - 2pm.
