Photographer Guy's hand-colored lens captures the Basilique du Sacré-Cœur in luminous white against a warm golden sky, its Romano-Byzantine domes hovering above the sweeping terraced gardens and grand staircase of Montmartre — the broad triangular lawns and arched viaduct below giving the composition a dramatic, receding geometry that draws the eye upward to the gleaming travertine façade. Published in Paris by A. Lecomte as number 14 in the "Paris et ses Merveilles" (Paris and Its Wonders) series, this unused French real-photo-style colored card likely dates to the late 1920s through 1930s based on the photographic style and fabrication details. The back states "Fabrication française — Reproduction interdite," asserting French manufacture and copyright. The card's back shows scattered blue ink spotting but the front image is vivid and largely unmarred.
