Signed pyrite stoneware vase

Beautiful stoneware vase with a nice pyrite glaze in beige and brown tones and concentric striations that give it a lot of charm. It has beautiful, harmonious proportions. It probably dates from the 60s or 70s when this material, probably Puisaye stoneware, and these natural colors were very trendy. It is a beautiful artisanal work of throwing and glazing. It is signed underneath, with an A with an additional bar incised in the material, but for the moment I have not managed to identify the ceramist behind this signature. It is in perfect condition, no cracks or chips, but has some original swellings which add to its charm while confirming the artisanal origin of this vase. It measures 12 cm in height, 7 cm in diameter at the top, 11.5 cm in maximum diameter approximately.
