I recall an illustration in the endnotes of the Kingdom Interlinear (I think. Its been well over thirty years) which is of a man being crucified on a pole. The WTBTS use a quotation from the author of the book in a misleading manner. The author does not support the idea that 'stauros" ( pronounced stav-ROS in modern Greek) means "torture stake" or that Christ was executed on a pole.
I remember seeing that before too.
