I haven't, but thats what makes it so weird of an image, since its possibly cannon.
Aggravate, Anger, and Piss off
Once more, I don't really see Luffy obtaining a bounty this arc either, especially when he's a 400 million pirate vs a 300 million mad scientist; however, due to him and crew having arrived on a quarantined island, having eluded Smoker (almost gauranteed), and having defeated Caesar and gang and revealed a fraud in the WG/Marines and Shikibukai on a NW scale, not to mention the possibility of Smoker discovering Law and Luffy's alliance, it IS possible that the end of this arc Luffy and crew will receive increased bounties to reflect a greater threat level.
A common mistake that people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools.
The afro-haired one could be Jozu and the other one on his left Marco ^^
