The 2 B's in BB stand for Jeff Blyth and Richard Biehrenheidt. They started to produce plates in the late '90s, and these plates were as good as you could possibly ask for, with smaller grains than the old standard of the industry, the Agfa Holotest 8E series, and more readily atainable than the Slavich PFG-03 materials. They were the hands-down winner in the Holographic Consumer's Report in the year 2000,
Colour Holographics took over the production in the early 2000's, check out their web site for details.
