Signed in relief in clear glass base insert. Great authentic burmese shade. Base measures 2 7/8" diameter and 1 1/2" tall, shade is 2 3/8" diameter and 2 3/4" tall, overall is 3 3/4" tall. I have used it and it looks great. Glows appropriately under blacklight....both pieces are period c1870 or so. Other than very slight roughage to feet of clear base these are in excellent condition. Great to use/and or display.
