You may actually be in luck with Pearls and Pearling Life by E.W. Streeter soon! Hesperian press is currently preparing a reprint. I am not sure when it will be released, but I imagine it won't take long.
Also...
There was an original at the Bernice P. Bishop Museum of Natural and Cultural History, but the condition was reportedly so poor it was crumbling. I guess there are not a lot of originals that have survived.
There was a replica created at the Etherington Conservation Center. You can reach them by email at
