50th birthday time capsule ideas........?

My husband will be celebrating his 50th birthday soon. I am planning on saving the newspaper from his birthday to put into a time capsule for him. I will also be burning a cd with some of his favorite songs from this year and last year. His hobby is fishing and I'm adding some pics of the fish he's caught in the past few years. Also adding pics from our vacation last year. I'm having trouble of thinking of some clever, unique items. Any ideas?
