Problem - no problem

An overturned boat indicates "problem - no problem" to be read according to the direction of the reversal: it seems to respond to these strange firefighters who are climbing towards the clouds...

A boat placed upside down on top of another is marked "problem" (if it is upside down) or "no problem" otherwise. She is upside down on a boat right side up: perched on a rickety cart: so “problem” or “no problem”? This is perhaps the question these firefighters are asking themselves: if they are there with their large ladder, is there a problem... or no problem? If we consider the question carefully, there is still a problem somewhere.
