Independent Phonograph Record Production
Настоящее имя: Independent Phonograph Record Production
Seems to have been an umbrella company founded and directed by Sárossy Szüle Mihály in New York sometime after 1956. The company was based at 170 Broadway New York, NY, specialized in releasing only Hungarian language records that might not have been properly licensed from the original record companies/labels and/or performers.
Also, the label seems to have included sub-labels as Duna Records (2), Sunshine (20), Bartone Record Co., Bartone, and quite possibly Csillag Records and Hungaria Univerzális.
No more information cannot be verified regarding the label and its sub-labels.
