Taking a break from Christmas shopping in the Florence Mall in 1989, I spotted it on the shelves at a B Dalton bookstore. I didn't buy it that trip (because, well, I was supposed to be shopping for other people), but scampered back to the mall and bought it a few weeks later, once I'd gotten together an assortment of cash, gift cards, etc, from family members; bought the core book in January of '90, and haven't looked back.
