Having discovered that I packed most of my very important... as in ANY T.P. book, in my moving experience and *Horrors* cleaning. I am ordering them from online booksellers so I can reread them and present the extra copies to my baby sister and her betrothed.
I found the dedication in Sourcery, printed in 1989 about the Birth of the Luggage.
"Many years ago I saw, in Bath, a very large American lady towing a
huge tartan suitcase very fast on little rattly wheels which caught in the pavement cracks and generally gave it a life of its own. At that moment, the Luggage was born. Many thanks to that lady and everyone else in places like Power Cable, Neb., who don't get nearly enough encouragement."
I was 19 when she was born and got the privilege of driving Mom, (and her) to the hospital, letting Nurses know in no uncertain terms that after 5 children my mother DID damn well know when she was in labor, AND got to tell the guards at the Belvidere Chrysler assembly plant that they had Better find my Step-Da (Chop Chop!) or there would be Hell to pay.

All in all twas in interesting day.
P.S. Baby Sis is a Fair Skinned, Red haired, Almost completely Irish Vixen with Blue eyes and we have to frequently dip her in complete sunblock kept in a 55 gallon drum. She has a temper to match.. LOL
Aha! So, Bob's yer uncle... very clever.
