[Scriptoris] ISO a Book on White Vine work

[Elaine]

Some years ago, a (now deceased) mundane friend had a book devoted to  
a study of White Vine work, popular for only about 30 years in the  
last of the 1400's. Would anyone have run across it and maybe, just  
maybe, gotten the title down?

White Vine is the design that has--well-- white vines curling in the  
margins and some Versal blocks. It is distinct from "white work".

Thanks in advance,
