Cake Design & Decoration by L J Hanneman & G I Marshall 1955 VGC 262
pages,larger format hardback.
The ultimate book on Icing,decoration and design of cakes.A really
superb manual,I would guess it's aimed at the professional rather than
being a hobbyists book.Packed with illustrations ,diagrams etc. Two
"books" or sections,the second being on more advanced work.
