The core of many Tiffany Favrile glass collections is often a Jack-in-the-Pulpit vase. The quality varies from example to example. This one has all the qualities to look for in a desirable example. It's tall, 20"; the mouth is large; the iridescence is strong; the condition is excellent (with a few minor scratches around the foot). Engraved signature on the underside. Tiffany produced Jack-in-the-Pulpit vases to impress and this one fits the bill.
