It is proposed that there exists a class of pulsars, called weak pulsars, forwhich the large-scale magnetosphere, and hence the gamma-ray emission, areindependent of the detailed pattern of plasma production. The weak pulsarmagnetosphere and its gamma-ray emission are uniquely determined by just threeparameters: spin, dipole, and the spin-dipole angle. We calculate thissupposedly unique pulsar magnetosphere in the axisymmetric case. Themagnetosphere is found to be very close to (although interestingly not fullyidentical with) the magnetosphere we have previously calculated, explaining thephenomenological success of the old calculation.  We offer only a highly tentative proof of this "Pulsar No-Hair Theorem". Ouranalytics, while convincing in its non-triviality, is incomplete, and countsonly as a plausibility argument. Our numerics, while complete, is dubious.  The plasma flow in the weak pulsar magnetosphere turns out to be even moreintricate than what we have previously proposed: some particles, after beingcreated near the star, move beyond the light cylinder and then return to thestar.
