Let me start the bidding...
I got 10 (yes, 1st editions!!!) coming, willing to part with 4...
$50ea for the ruler, bare. $150ea ruler + original envelope (likely touched by Dave himself or family member!!!) only two available.
This is a once in a lifetime opportunity for eevblog members only. Unsold inventory will be sold on ebay for 10x this, act now!...
