We had photos on display at my parents' 50th anniversary party. I think there were some photo albums from their wedding, plus some collages of them over the years, many of which included kids, grandchildren and close friends.

We had cards for people to write something to them, which were set out in advance at each of the tables. My sister-in-law put together a scrapbook afterwards which I think includes the cards (or a selection of them maybe, I don't know since she only finished it recently and I haven't seen it yet).

The food was buffet style so there was no assigned seating.

My brother gave a speech, as did the best man.

We had a boom box paying CDs for music.

There was lots of picture-taking -- various combinations of family members, wedding party, etc.

I went around and took photos of most of the guests as they were sitting at the tables chatting. My mother appreciated this, since she had not been able to get her own photos of many of those folks.

For the cake, the bakery decorated it with a copy of their wedding picture. It was on something edible, made from rice I think?
