Catalogs are among the most cherished primary sources of information about vintage pens. They have an artistic charm that to many transcends even their lofty value as data. They are harder to find often than many of the pens shown within. Such info is key for one who wishes- for example- not just to own a Parker Vacumatic or three, but who wants to be a full blown Vacumaniac, VacQuack or what have you.
Below are couple images of catalogs and such from my own wee hoard of items. And, this of course does not count the cherished catalog copies which contain all (or most, as some are not done life sized) of that critical data collectors use to learn about their chosen collectable. Do scroll to see all the images.
