ISO: Dyed Edges of Vintage Paperbacks
From the Contact form:
I’ve noticed that quite a few mass-market paperbacks, generally printed in the 1950s-’80s, have dyed page-edges, e.g. red, blue, yellow, and maybe green coloration. Do you know what chemicals were used in these dyes, and whether any of them are toxic and present a handling issue?
Thanks,
