U.S., World War I Draft Registration Cards, 1917-1918

Validator (claude-sonnet-5-5, 2026-10-28): supports, confidence 4/4, tier record.
The image of the original WWI draft card is readable. The name is written and signed as Vaclav Taubr, a normal Czech spelling of Václav Tauber. The birth date of 17 Nov 1876 with age 41 is consistent with the claimed 1876 birth. The record supports the name; the death year is outside what it can show.
Matches: Registrant's name is written "Vaclav Taubr" on line 1 and signed "Vaclav Taubr" at the foot of the card, a Czech form of Václav Tauber; Date of birth November 17, 1876 and age 41 agree with a person born in 1876; Marked naturalized citizen, consistent with a Czech-born immigrant; Wife named Francis (Františka) at the same Chicago address (4845 S. Honore St); Registered in Cook County, Illinois (Cornell Square Park local board, Chicago), matching the citation detail
Limits: The claim is only the name; the card gives the spelling "Taubr", not "Tauber", and no diacritics; The card does not show a birthplace or death year, so it cannot confirm the 1956 end of the 1876–1956 life span; Identification with this particular Václav Tauber relies on the birth date and wife's name matching the database person, which the card alone cannot prove
