Particular Model, Year? Collection?
I mainly collected in the 90s because the catalogs were oversized (I believe 9 x 12) and thick (some are 300 pages or more) I do have some catalogs pre 1990, but these tended to be thinner and I was not as crazy for the styles. Around 2000 or so, they did series of hardback catalogs. These were also limited and numbered (x out of 3000), but still large, as well as a couple of them had a ton of fold out pages.
Around 2002 or so, the catalogs got much smaller, or at least the ones I came across, and started to be a collection of smaller 8 x 11 or smaller books of 40 - 60 pages. I have some gaps in here, but in general I have about a bookshelf and a half of Escada Look Books.
