Lynda Carter (yes, that Lynda Carter) posted this on Facebook the other day, and a friend tagged me when he shared it. It's apparently from the episode "The Boy Who Knew Her Secret." Despite being a huge comics nerd, I've never seen the original Wonder Woman TV series.
The longer I look at this photo, the more I see.
On the one hand, the horse is nicely relaxed and alert, she's got a nice soft hand on the reins, and she's riding with a ton of confidence.
On the other hand, George Morris would have a heart attack. No hairnet, much less a helmet! Riding in tights (imagine the runs?!)! Gripping with the knees and tipping forward badly - no real depth of seat, she's rocked forward on her thighs instead of sitting on her seatbones.
On the other other hand, as my friend pointed out, she's an Amazon. She can do whatever she wants!
