In 1898, the Maison Mumm built their new champagne cellars ("caves") at Reims. The façade's main door was ornate metal surrounded by Falconnier bricks, which are now sadly gone. The first three images are period postcards, and the last, showing the entrance as it appears today (sans Falconnier bricks) is by Jacques Mossot, dated March 2008; it appears here courtesy Structurae.
