Plate signed Luis Janeiro, Portugal, enamelled terracotta plate

Pretty dish or large plate in terracotta whose floral decoration has been chiseled then enameled in white and blue tones. It will be perfect as a wall decoration, alone or in accumulation. But it can also be used in contact with food if I believe the small symbol engraved on the back (a glass and a fork). It is a beautiful artisanal work of luis janeiro artisan potter in sao pedro do corval in portugal, it is signed on the back. It would date from the 80s or 90s, without certainty however. I also see a word engraved in the enamel on the front face, but I can not decipher it. It is in perfect condition, no cracks, no chips, not even a chip. Note a small original defect (see last photo) on the back. It measures 29 cm in diameter and 4.5 cm high.
