Compete to crack secrets lost to history—for fun, clout, and (no) profit
The card openly says Dear Darling and addresses Henry Wulf in Bennett, Iowa. Thirteen principal groups contain 80 numbers, several continuing across physical line breaks. Other pencil numbers, an open date, and faint marginal afterthoughts belong to separate layers. A complete result for the principal groups cannot honestly be described as a reading of all those marginal marks.[1]
The mechanism is reversed alphabet numbering: each value n gives alphabet position 27−n, so 1 is Z and 26 is A. The exact repeated ten-number group 8-4-22-22-7-19-22-26-9-7 reads SWEETHEART. That repetition was kept as a predictive control. Two independently repeated 19-22-13-9-2 groups give HENRY, and 16-18-8-8 gives KISS. These agreements fix one table across the main field.[2]

In particular, the end of the tenth group and all of the eleventh continue as SWEETHEART ABIE. That is the basis for the affectionate sign-off, not a reason to identify a person named Abie in advance.
A KISS, to REMGET, [4-2] Dear Darling, SWEETHEART, HENRY D. WUNF, for HWSGAND, HENRY, How is my SWEETHEART, HEARY getting along now.

All 80 principal values decode and encode back exactly under the reversed table. The source reader resolved two previously bracketed parts of the long tenth group by comparing native allographs: a 9 is clear, and an apparent merged 28 is actually 7 followed by a hyphen and 26. Those are physical transcription corrections. By contrast, WUNF, HWSGAND, HEARY, GAD, and MORNIKG remain what the source says.
The address makes WUNF plausibly intended as Wulf. “Husband,” “Henry,” “bad,” and “morning” are editorial interpretations of the other anomalous blocks; their source letters have not been replaced. REMGET has no demonstrated expansion. The faint final ordinary phrases and marginal numerical afterthoughts remain unreadable as complete sequences. The numerical result does not establish a legal marriage, the sender’s identity, or the meaning of the separate open 4-2 date.
The source-secure cancel is Bennett, 22 March 1916. Davenport is part of the printed Government Bridge view, not a proved postal origin. On 29 August 2026 HCP marked the card “Not solved” with no key or plaintext. The bounded audit found no exact prior solution, same-hand/key sibling, or DECODE crosswalk. The supported result is new to those checked exact-item sources, not an assertion of universal first priority.[3]
