Pat Mills on the history of girls' comics in issue #5 of "Comic Heroes"

"Another male writer was Joe Collins, who scripted 'Becky Never Saw The Ball' - about a blind tennis player! I used to treasure it as the most bonkers girls' story of all time, alongside 'Bunty''s 'Limp Along Lindy' and 'Flipper Feet' (a girl who's a champion swimmer thanks to her huge feet). Although I learned recently that they've all been surpassed by another 'Bunty' story called 'Penny's Pogo Stick'. It's World War 2, and Penny's dad is a top rocket scientist in Poland. She hides his rocket formulae in her pogo stick and pogoes her way across Nazi-occupied Europe to freedom."
