Here is an antique cast metal art nouveau incense burner or potpourri bowl made by K and O Co. (Kronheim and Oldenbusch Company).  It has a removable lid and is covered in exotic motifs and cold painting in multiple colors.  Condition is very good with only minor chips to paint and some discoloration from heat on the interior.  It measures approximately 3 1/2” tall x 2 1/2” across.  See photos for overall condition and ask any questions you may have.
