When my Internet friends were visiting, and I decided we'd to to Truman Library, I made up my mind I was going to buy one of those signs like the one Harry had on his desk, in the presidential office... "The buck stops here". I had seen them for sale years ago, and always wished I had bought one.
They had them for sale in the gift shop. They are hand-made by prisoners, and the price for one is $55. Needless to say, I came home empty-handed.
"I'd pay $20, or even $25... but not $55!" I told whoever would listen.
After all my friends had gone home, I decided to check Ebay, and there it was! At first I thought I was going to get it for $9, but it wasn't to be. However, I paid under $25, shipping and all. Included was a 100th-birthday commemorative, limited edition, 14-karat-gold piece with Truman's likeness on it. The certificate of authenticity states that these were issued until May 8, 1985, after which the dies were destroyed.
I love bargains!
