Compete to crack secrets lost to history—for fun, clout, and (no) profit
The portal shell identifies a German card to Hedwig Zipfel, dated 5 March 1901 and routed Kiel to Zeitz. The attached image instead has a French address to Mlle Madeleine Boucheron in Parigné-l’Évêque, Sarthe, ordinary French closing words, and two number lines. The picture side shows a cat and carries no further message. The label and image cannot be treated as one consistent witness. [2]
This source correction is part of the result. It separates the card from the German Hedwig/Hugo correspondence before any key is transferred. The French card has to stand on its own.
Ordinary alphabetical numbering, 1=A through 26=Z, accounts for both lines without a changed value. The repeated 6s become the double F, and every repeated 5 and 21 retains its value across the second word.
| Written number line | Letter-by-letter reading |
|---|---|
| 19 15 21 22 5 14 9 18 | S O U V E N I R |
| 1 6 6 5 3 20 21 5 21 24 | A F F E C T U E U X |
The entire concealed message is Souvenir affectueux, “Affectionate remembrance.” Replacing each recovered letter with its ordinary alphabet position returns all eighteen written numbers. The open ending reads Devine / de M., tentatively “Guess. From M.” The final initial belongs to handwriting, not to the numerical proof.
SOUVENIR AFFECTUEUX Devine de M.
The two decoded words are secure. The short cursive closing is reported as the source reading rather than expanded into a sender’s identity. Its likely challenge to guess the writer fits the wording, but the card does not answer that challenge.
The postmark visibly includes 25 and 6, but its year is not securely legible. The contradictory shell’s 5 March 1901 date must not be assigned to this image. Nor may its collection suffix or German recipient be used to connect Madeleine with Hedwig or Hugo.
The 28 August 2026 provenance audit checked the exact IDs, catalogue names, French address, distinctive phrase, local corpus, and relevant published collection discussions. It found no source-level public result repairing this mismatch or giving this complete reading in the reviewed surfaces. That supports a bounded catalogue correction and independent item reading, not novelty of A1Z26 or universal first-ever priority. [3]
The German residual now separately cataloged as Problem 135 is not solved by this result. Its evidence and unfinished reading remain separate.
