Bulgarian pottery box "Trojan"

Pretty vintage box in glazed artisanal bulgarian pottery called "trojan". Slightly flattened circular shape with lid with a small handle. Brown red earth, "dripping" patterns in ocher, navy blue, black and white tones. Stamp under the bottom very difficult to decipher. 14cm max diameter, approximately 7cm max height with lid, 5cm without. Very good general condition, nothing notable, the lid does not hold its place well. Around 800gr.
