I feel compelled to observe that Poster Doctor is in no way a
Doctor, at least not one who subscribes to the Hippocratic oath.
Hydrogen peroxide is a powerful bleach.  Used improperly, some say
even used properly, it causes serious, irreversible damage to the
paper, as well as many of the printing inks found in modern and
vintage posters. Poster Doctor needs to show his patients some
respect and go to medical school.
