Little Vintage French Cup with Blue Design

A really lovely little Terre de Fer French coffee cup with a gorgeous deep blue transferware design of flowers and garlands - it has an art nouveau feel to it. The stamp underneath says 'Terre de Fer' 'Au Planteur de Caiffa' 'Guirlande' 'M' '12' - perhaps it was from the famous coffee store and grocery store of that name.
This is certainly full of character with a lovely buttery and worn patina to it.  One old chip to the rim (see image) but watertight and no cracks.
It measures 6cm tall x 6cm across the rim
