Here is a collection of sketches from GDT’s wonderful notebook. GDT offered this description of the books from a February 18, 2007, post on the DTF message boards:
I got the journals in Venice in 1997 (while promoting MIMIC) and I looked for them again last year. I couldnt find the shop and – althought I found some similar ones- could NOT find anything remotely as discreet or attractive. I like them because the thickness of the paper is JUST SO and allow me some acryclic, ink etc and it is smooth enough for fountain pen writing.
Here is a video of GDT talking about his notebook on SHOOTOUT on AMC.
