1960s Chinese Wushu Question

[TopCrusader]

I stumbled upon these old Chinese Wushu pictures on a Chinese language page - best I can tell it says it comes from the PRC from 1962 but I did not see it mentioned where these were published (book name, magazine, etc?) If anybody has any idea on the original source of these vintage wushu pictures please let me know, thanks!
