From CigarCyclopedia.com:


In honor of Stanford Newman’s breakthrough use of Cameroon wrapper on his Cuesta-Rey line in 1963, a 40th anniversary cigar was planned for 2003. The Cuesta-Rey “Stanford’s Cameroon Reserve” appeared for the first time in the Pyramid No. 9 shape (6 1/4 x 52) in a special Cuesta-Rey humidor in 2004, then had limited retail exposure in a run of 35,000 cigars in 1,750 boxes of 20 in 2005. A second size, also with a Cameroon wrapper and Dominican-grown binder and filler, was produced in the Churchill size (7 x 49) in 1,000 boxes of 20 in 2006. There are a few of each still on the market, but they’re essentially gone.
I, too, had thought they were all gone.
