Years ago, through an autograph dealer in New York, I bought a little rolodex-style Barclays bank card for $150, a card that had once been issued to John Lennon. This little card stated that anything under $200 in Lennon’s account could be withdrawn by his two lawyers without permission, but over $200 must be authorized by Lennon.
The card was signed by Lennon and the two lawyers.
I held onto this card for quite some time, but decided at some point to see what someone might pay for it, so I put an ad in an Ottawa paper, wondering what kind of offers might come up.
