What the card says
An editorial summary of the readable passages, rather than a complete translation of every sign. The sender remains unidentified; the nickname and similar language across cards do not establish a single writer.
The partly resolved Czech suggests an affectionate complaint about waiting every day for a promised letter. The following phrases ask whether the writer has given offence and possibly whether the addressee is ill. A note sent some days before and the hope of an answering letter connect the message.
A later image-only review interpreted the underlined pair rendered yi by the fixed key as the conventional numeral 14. This is a separate source interpretation, not a revision of the saved literal.
The inscriptions on cards 329 and 453 are exactly 14 calendar days apart. This makes card 329 a possible referent for the earlier note, but neither that connection nor a general rule for unencrypted underlined numerals has been established.
Saved literal readings
This is the saved decoding output. Question marks mark unresolved source units, which may be single letters, digraphs or uncertain groupings of strokes. Spelling defects, line breaks and source-region labels are preserved; proposed corrections are discussed separately.

What remains uncertain
- The possible illness, the exact wording of the questions and much of the closing depend on unknown completions.

1 March 1900 · inscribed date. The date label records its evidence source; it does not establish a posting or receipt date.
Marked signs on this card later contributed to the development of secondary rules. Any improved reading produced by those later rules on card 453 is a training replay, not fresh validation; only the first fixed-key output is displayed here.
The source transcriptions and language checks were AI-generated. No external human expert review is claimed. Coverage counts signs assigned a value, not verified correct letters; one sign can produce the two-letter Czech ch.
