Before Bangladesh existed, this was simply a Pakistani note — issued by the State Bank of Pakistan and circulating in what Islamabad called East Pakistan. The "People's Republic of Bangladesh" attribution reflects a brief post-independence administrative decision: after the 1971 liberation war, the new government overprinted or authorized continued use of Pakistani currency stocks on hand while its own notes were being prepared. The attribution in catalog records can mislead; the note itself was designed, printed, and originally issued as Pakistani currency, full stop.
The Pakistan Security Printing Corporation in Karachi produced this series across a remarkably long window — 1951 to 1967 — with relatively little variation. Notes that ended up in East Bengal saw harder circulation than their western counterparts, which tends to show in surviving examples.
