I still have shoe boxes full of hand-written on the back of business cards - timeslips. Yes, only ET and mph. No incrementals. I remember being WOW'd by seeing them for the first time. I thought "Man, we getting with MODERN stuff now!"

The funny thing is that the hand-written cards are still readable. The more modern timeslips' ink fades after a couple of years to the point that keeping them is useless. Well, I guess not any MORE useless than keeping 35 or 40 year old business cards with ET and mph scrawled on the back... with an occasional WIN written across the top.
