As a teenager, I had to make the tedious meetings a little more entertaining, I would often add my own touch to the silly photos or pictures in the WT articles or current study book. Examples of anachronistic items in Bible Times pictures easily added: cigarettes with a small wisp of smoke, a pistol, sunglasses, fishing rod, bloodshot eyes, cracks in structures, small aircraft outline with contrail... you get the idea. (with the right pen and a steady hand it did not look like obvious graffitti.
Sometimes the goofy gestures portrayed in the art was just begging for a touch-up. It was also fun to obtain another persons copy of the WT or book and make a subtle addition in the background and see if the person noticed.
Just wondering if anyone else tinkered with Holy Spirit inspired art.
