Dear Mr. Brown,
Per our conversation, I have attached a picture of the lamp and a close-up of the shade–you will see that the texture of the ceramic requires something interesting in a shade.  Originally, 57 years ago, it was a drum shade made of some material that had the leaves within (perhaps some fabric/plastic combination.  About 14 years ago I replaced it (the material started to fray on the outside).  This is paper (from Kate’s paperie in Soho) laminated.

I will be interested in your suggestions.
