Tri-color thick art glass bowl by Royal Doulton. White, green and blue. Comes with original box. Has manufacturers stamp etched on the bottom. The bottom has been smoothed out in 2 spots. Does not affect function of bowl. Have learned it came direct from Manufacturer that way. Have seen other bowl with same marks. Great condition. No chips, cracks or repairs.
