The website trasbus.com published scans of numerous ticket series, the closest to this ticket is described as "dated 1951". On 1.02.1951, Miejskie Zakłady Komunikacyjne was renamed MPK; as of 01.01. 1953, Miejskie Przedsiębiorstwo Busowe was spun off from MPK (to which streetcar and trolleybus lines were still to be subordinated).
If the term on the page referred only to the new name of the company in 1951, it is possible that the ticket is from a later period, under the name MPK the company functioned until 1964 (then the two companies were merged again and MZK was formed).
