I have corresponded with Samuel Shermans granddaughter and sold her dresses as she is cretaing an archive, as all his work was lost to the family....
I shall endeavour to find her email address....
he continued to work through the 70's into the 80's if I recall well....
labels were,:Dollyrockers'', 'Sambo', 'Clothes by Samuel Sherman', Samuel Sherman and one other I can't recall at present
hope this helps..
