"Princess Tina" is a group of three titles with related contents.
Denis Gifford reports that PRINCESS ran 30 Jan 1960-16 Sep 1967 (346 issues):
However, this information is not complete. In March 1967, the title was back to PRINCESS (not "PRINCESS & GIRL"). Before March 1968 it changed to PRINCESS TINA, possibly from Gifford's date of 16 September 1967, suggesting 346 issues to that point. PRINCESS TINA was formed through amalgamation with the title TINA, which ran for seven months in 1967. By May 1970 the title was PRNCESS TINA AND PENELOPE. In May 1971 it was back to PRINCESS TINA, which ended in 1973. There were probably other amalgamations and name changes.
