This:
This is the first 'old' card I ever got and it is the earliest acquisition left in my collection. I'd guess I was under ten and got it in a NYC antique shop. I'd never seen colors or designs like that because no cards in the mid-1970s were made using Flexichrome and that was my frame of reference. And it was bigger than my usual cards. I studied it for what must have been hours and I was hooked on vintage cards.
Now, would I sell it for life-altering money? Sure. Sadly, but certainly, and for enough money I'd even hand-deliver it. Ditto for my whole collection. In the final analysis, it's all just stuff, not friends or family. To paraphrase a song I like "Truth is I thought it mattered. I thought that cards mattered. But does it? Bollocks. Not compared to how people matter."
