Greek Wall Plate Raised Relief Design, Achilles vs Hector, 13" Vintage

Used, family owned since 1960s. I don’t know age. Terra Cotta raised design, handpainted in Greece. Plate has a wire hanger on back to hang on a wall. This plate is larger than other plates that are of similar design. This is probably a replica. There is a signature on back and date 600 BC. Plate has a cracked piece that has been glued back into position. Has some signs of wear: small chips or flaking on outer edge. See photos for condition and signature.
