Having just read the Donut Shop thread, I was reminded of the typical way my fellow publishers and I would deal with hard- or impossible-to-place issues of the Watchtower and Awake! magazines.
One in particular that comes to mind is the issue of the WT, released around the late 80s or early 90s, that depicted a close-up facial shot of an old man with tremendously bushy eyebrows. My friends and I affectionately dubbed him "pubic brow." I think the cover article was something like "The Great Issue Faces You" or at least along those lines.
Another one that comes to mind was the issue of the Awake! on boredom featuring a pink background with an enormous head shot of a nerd lethargically resting his head on his fist. You could clearly see every pore on that guy's face.
We used to come up with pet names for different issues of the magazines. Once in a while when we'd be searching for an appropriate back issue we'd recruit each other's help. The exchange went something like:
Pub1: "What back issues ya got?"
Pub2: "I got 'Pubic Brow', 'Nerd Boy', 'Date Rape', and 'Paint Chips'".
Pub1: "Throw me a 'Date Rape'".
Which magazines were especially difficult for you to unload?
