The Luggage opened the Philo decade in Spring 2010 and became the face of it, literally: the zip and feet arrange themselves into an expression no other tote has, recognizable across a street, which is most of why it conquered the street-style era. The sizes tell the decade's story better than any essay. The full tote came first, then the family shrank through Mini, Micro and Nano as the whole industry's size pendulum swung, so a Luggage's size is a rough date all by itself.
The Slimane era retired the model, and the discontinuation did what discontinuations do in this market: fixed the supply and converted an It bag into a collector file. Every surviving example is Philo-era by definition, which means every genuine one wears the accented logo.
A Luggage marked CELINE without the accent is wrong by construction: the model and the unaccented logo never coexisted. That one check outranks any stamp reading.
Celine hands the dater a gift no other maison offers: in September 2018 the house removed the accent from its logo, citing its own 1960s collections, so a bag marked CÉLINE belongs to the Philo era and earlier, and a bag marked CELINE is September 2018 or later, full stop. An accented logo on a Triomphe, an Ava or a 16, models born after the change, is a contradiction no serial stamp can rescue. The interior stamps themselves do not read as a calendar, so date by era instead: the logo form, the model's documented birthday, and the size roster of its year, remembering that sizes have birthdays too, like the phone-dimensioned Teen Box of 2018.
