Girls Hockey team includes Winifred Mardon (1905-1989) (front row, second from right: holding stick). Winifred attended PNGHS but this photo doesn't appear to match other PNGHS sports photos of her era. Possibly Methodist Church (Cuba St) hockey team?
Likely to have been photographed at The Crown Studios.
No names included on the obverse/reverse sides of the card mounted image.
Winifred's brother, W Mardon is in another hockey photo: 2017P_IMCA-DigitalMaster_019936
