VTG JOME Czechoslovakia Porcelain Mug

Vintage mug featuring an image of a boy and girl sitting on a bench. Their backs are turned to one another and there is a knife stabbed into a painted heart. The girl may be writing something, and a black bird looks down at the boy from a nearby branch. Measures 3.5" tall Gold trim adorns the rim, handle, and accents along the sides. Backstamp reads: "Made in Czechoslovakia" with "JOME" in the middle of a stamped image. Research leads me to believe this may be short for "JOhann MEnzl" and that the mug bay be from the 1930s. Please view photos carefully for condition.
