The endgame is to raise attention to international jewry but it would have a greater effect than, for example, the (((coincidence))) thing, since it would be more covert and pretty difficult for them to find out what it means. Those abstract (((pictures))) would force them to really fire their neutrons, which in the end would leave a lasting impression on them. The MSM would be like: "Various mysterious pictures spotted in town X"
or "Mysterious pictures reach town X", "What is the deal with those mysterious print outs?"
