Ideas for 50th anniversary of acquaintance?

Under a Palm Tree
Hoping I can get some ideas. Dh and I have been invited to the 50th wedding anniversary party for a friend's parents. These are people that we see maybe 2-3 times a year and make a small bit of idle chit chat with. Don't really know anything about them but we are being invited and attending because of our friend.

Can someone give me some ideas on a gift or what we can take? I don't have a lot of money to spend, and really don't want to spend much because its not someone that I even really know or spend time with. Thanks!
