Dear Categorists A few days ago someone asked me for a copy of the 1972 Christmas Letter Max and I sent out to category theorists as a precursor to SLNM420. I had thrown out all but the original typed manuscript which I have just scanned and put at: <http://www.maths.mq.edu.au/~street/Christmas1972.pdf> should anyone be interested.
