Doc Records
"Doc Records" part of H.R.B. Inc. in Rydal Pennsylvania. In 1963. HRB, owned by Helen Blumberg, was formed as a nonprofit Pennsylvania corporation who copyrighted in October 1963 the Doctor Shiny-Teeth dental kit for boys and the Doctor Shiny-Teeth dental kit for girls. Revere Press Inc. took Helen to court over Copyright material in 1968, so maybe that was they end for Dentistry and music for this label
