I bought this years ago on Ebay. I just bought it because I really liked the picture.
It's about three feet wide and on some sort of vellum. On the back it says: "A Cartoon for Our Bl. Lady's Oratory, The Circular Hall, Taunton"
It's all very odd - I can't find any records of either an Oratory or a Circular Hall in Taunton.
I've no idea where the sketch is from. It shows the annunciation with Gabriel holding a fleur-de-lis followed by some odd cherubim. Zecharish in the background is being comforted by another angel.
Any art-y types with any thoughts about it?
