The greece magazine "Athlitis" has its editions on pdf where you can view or download them. I don´t understand greek, but it is not that hard to navigate.
There are 3 magazines with lots of editions to choose. Athlitis (editions until 1992), Bodybuilding (from 85 to 89), and Bodybuilding/Fitness (from 1998 until 2018).
Sure they cover a lot of male bodybuilding, training etc. But there are some nice contest pictures, especially Wabba and Nabba from the 90´s. It may have to do some research, but its worth it.
