Objects associated with the College? A couple of things spring to mind - I joined the Queen's women's rowing team - and we almost won an oar but didn't (bumped on three races but not on the fourth) - big disappointment at the time. It would have been very nice to have an oar with our names on it!
I was doing voluntary work with an after school club in Blackbird Leys. I brought a small group of kids to visit me at the Florey Building and they thought it was a space ship.
