I love your layout. My aunt goes to a 40s weekend up at Pickering Every year... It's on the 11th October this year if memory serves, you'll probably get a cart load of stuff there.
I love the music of that era, and also I think of spy's, Bletchley Park and Enigma... Morse code and hidden pockets with code words would be great to hunt around your album for.
Ooh... Violet.... What's her name?... "The life that I have," was her code. A very brave woman.
Best of British with your album and I'm sure it will look wonderful!
