I recently purchased on e-bay some graded printing paper manufactured for Zone VI.  100 sheets of 8x10 and 50 sheets of 11x14.  Here is a print I made over the weekend and then lightly toned with Selenium.  The 8x10 paper was from a local fine art photographer who had it stored in his freezer since 96'.  I tested the paper for fogging and it was fine.  The box of 11x14 was pretty beat up and the seal broken.  I'll test it this weekend to see if it's okay.
