Sugar or mustard bowl Anfora Agueda hand painted ceramic Portugal

This charming ceramic sugar or mustard bowl features a delicate hand-painted decoration. It comes from the anfora company, which has been producing high-quality tableware for hotels, restaurants and individuals since 1920 in agueda, portugal. The hand-marking underneath also indicates the number 56. It is a set consisting of the container, the lid and the small plate. It is difficult to date it, perhaps from the 1950s given the lines, the cut corners in particular, which recall the codes of art deco. I asked the company by email, if I get an answer, I will add it here. The set is in good condition, the only flaw is a chip under the plate that is barely visible when it is placed on a table. Apart from this, no wear, no chips, the decoration is not erased. The plate measures 15 cm by 12.5 cm, the container measures 14 cm by 7.5 cm for a height of 6 cm. The total height of the 3-piece set is approximately 12 cm.
