Geller created a new poster for the '2nd International Symposium on Ceramic' for the oral design. The logo for the first poster was produced by Geller on a lettering sheet (like a sticker where the letters are rubbed onto a film). He wrote the 'oral design logo', added a picture and sent it to a printer who produced posters in large and small sizes. The larger poster was displayed at the exhibition, but Geller took the smaller one home.  The posters still hang in my house.
