1928: Friedman's Coded Holiday Gram

Sunday, December 24, 2023

It's December 1928 and Elizebeth and William Friedman sent a coded holiday gram to friends and loved ones. The codebreaking couple fortunately included a grille overlay that with a series of quarter turns would reveal the complete message. The full message reads..."For Christmas greetings in '28; Brings you word of xmas cheer; A crypto telephotogram here; We use a means quite up to date." Happy Holidays!

In 2017, Bill & Jew-Lee Briere celebrated the Friedman couple's anniversary and created a crypto-cablegram in their honor. Click the link below to learn more and see if you can solve it!
