Jovian weightlifting challenge.
Image 3 success.
This showing notable for several reasons.
One is that, just the previous issue, Diana was on Jupiter with NO difficulty with the gravity.
Two, we see here Wonder Woman doing something MORE difficult and strength demanding than standing alone to get AROUND the supposed difficulty of standing on Jupiter.
Three, this parallels the difficulty Superman had with high gravity environments, namely Krypton, or even Braniac's original bottle of Kandor.
I have to check the dates to see which happened first, though.
