What's Lurking in the OCIAM Drawers?

While trying to find an envelope to mail stuff (none in the mail room), I check in the drawers under one set of Mathematical Institute printers, I found reams of paper (of course), a few technical books, a book about what to do if one gets pregnant, and the supply of the old (from more than a decade ago) OCIAM t-shirts.

I couldn't find an envelope large enough to mail the book I want to send, but I wonder if the t-shirt that I bought almost 9 years ago was the last new one anybody acquired.
