100 Years Old

My great grandfather is turning 100 on March 27th. String Bean and I are going out to Seattle to celebrate. I am looking forward to getting a 5 generation photo while we are there! That's pretty fun because when I was about String Bean's age, I was the 5th generation in a 5 generation photo with another grandfather of ours at his 100th birthday party.

I'd like to get something small for him for his big day. Any ideas? He's 100, so I don't think he needs anything. Apart from ordering a card online, I'm having a hard time finding a happy 100th card.
