This antique Korean serving tray would have been used for serving tea or individual meals. The signature characters on the bottom are followed by the symbol for "student", presumably the tray was carved by an apprentice. The bottom also has rough darken areas for a more secure gripping surface and shallow attached feet which also have rough bottoms.
The tray has a delicately upturned lip, a deep rich red brown color. It is approx 13" x 9.5 inches. No cracks or chips but the surface does have a few scratches which do not show in the photo but which are appropriate in a utilitarian wooden serving tray of this age.
