La Poste’s twelve-stamp photography-bicentenary booklet is scheduled for 9 November 2026. Produced with the Centre des monuments nationaux, it uses views of the Panthéon to explore changing photographic techniques and ways of recording the same monument.

The operator describes a progression through cliché-verre, paper prints, photochrome, reversal processes, silver-based photography and digital imagery. The booklet forms part of the photography bicentenary organised by France’s Culture Ministry from 1 September 2026 to 30 September 2027.

The self-adhesive stamps are printed in photogravure. La Poste lists the booklet at 264 × 68 mm, with twelve €1.52 Lettre verte stamps and a total price of €18.24. The stamps have permanent validity for the 20-gram service. Its image credits name photographers and collections associated with the Centre des monuments nationaux.
