Golden Alice 2016 for Encrypted Postcard

Tobias Schrödel provided me a set of twelve beautiful encrypted postcards – one for each month of the year. In other years, this series would certainly have won the Golden Alice in the postcard category. However, in early 2016, an even more outstanding post card set came to my attention. It’s the greatest encrypted postcard collection I have ever seen: the 44 postcards sent by Josef Fröwis from 1898 to 1900.

I’m very thankful to the Bregenzerwald Archiv for providing me this cryptologic treasure.

 

Golden Alice 2016 for Newly Discovered Cryptogram

The most notable unsolved cryptogram that has come to my attention in 2016 is a bottle post from Western Russia. I call it Kalinigrad’s Second Mystery (after the famous Amber Room mystery, which is connected to the city of Kaliningrad, too).

Kaliningrad-Cryptogram

So far, nobody has solved this strange cryptogram. Any help by me readers is appreciated.

 

Golden Alice 2016 for Newly Created Cryptogram

The cryptograms I introduce on Klausis Krypto Kolumne usually have a historic background. I usually don’t publish cryptograms that were created as a puzzle to entertain people. However, there are exceptions. For instance, if a cryptographic puzzle refers to a method of historic interest (e.g., the double columnar transposition or the M-138), I consider writing about it. In addition, I sometimes write about crypto puzzles that are integrated in nice pictures or other art work. The most interesting of this kind I saw in 2016 was provided to me by Tony Gaffney. It’s a message hidden in a photograph showing chess players:

My readers loved this challenge, they wrote many comments about it. Finally, they found the solution. Thanks to Tony for providing me this crypto puzzle and thanks to all the readers who contributed to solving it.

 

Congratulations to all the winners! I am looking forward to writing many more blog posts in 2017.

    Congratulations to Norbert and Christoph for their codebreaking!

    Maybe in 2017 somebody will tackle the Kaliningrad bottle cryptogram. There are some hints that it is a transposition of german plaintext, perhaps a computer aficionado could do it f.e.with a hill climbing routine.

    Very cool list. Happy to see you mention Code Warriors. It is sitting on my “to be read” stack. 🙂 Happy 2017!

    Kaliningrad, Russia, previously known as Königsberg, is also the site of a famous mathematical puzzle.
