We had planned a slipcased set, but unfortunately a production problem resulted in the heights of the three volumes being marginally different, which meant the slipcases didn't really look good enough. A few prototype empty slipcases were produced, and I think that as we had them we sent a couple out to people who wrote in at the time specifically asking for one, but as far as I can remember we never did a production run. We ended up producing a much more successful trilogy of combined volumes without the anguish of Bible paper, leather binding, and all the production headaches those things entailed! We did release that set in a slipcase for a while.
