For the K/S Advent Calender 2011
From the prompt: On Christmas Day, Jim and Spock celebrate their 50th wedding/bonding anniversary.
(Ok, I have to be honest: I had real trouble trying to scan this picture on my scanner; it was WAY too big and I had to cut away edges for it just to fit :(. I hope it still looks nice though )
So this is like one of those wedding renewals and this is a decorative picture at the event.
