I cut this out of a flex or mf mag way back in the mid 80's and have kept it in a photo album for over 20 years for inspiration. I still like looking at the huge disparity between the two arms. Remember, this was printed back when 20" arms were pretty unusual and definitely something to brag about. The 20" arm looks kinda short to me but it looks about perfect to me in ratio of bicep to tricep to forearm.
The scan isn't the best but the picture got wrinkled over the past 20 years.
Enjoy
