random acts of generosity

One of the loveliest surprises I've had in ages, and almost entirely anonymous (perhaps I'm being dense, but the initials were no help at all). I know you didn't do it out of any desire for reciprocity, but I'd still like to lavish similar kindness on you, all the same. If the photograph was your own, it's bloody marvellous. Also, I'm thoroughly bemused by the lack of postmark. Anyone care to own up? Or say hi via screened/anonymous comment? I am intrigued by you, mystery person!
