I remember this booklet!

I remember this booklet!  It was sitting on my dad's desk, down in our basement.  It's funny how your brain can dredge up details about a long-ago event, given the tiniest of nudges from a photo, a smell, or a sound.  In this case, I remember not only the booklet itself, but also the ballpoint pen that lay next to it: black with a silver metal parts (the tip, the button, the clip, and a ring around the middle), some silver printing on it (an ad of some kind), and a distinctive and peculiar odor.  This must have been around 1960 or so.  I wonder why my brain thought that particular little piece of data needed to be filed away?
