Where are the wanted posters on zubo?

if you go down to the lower quarry then keep on going until you see a fire with a TNT barrel pick up the TNT barrel and drag it until it reaches the blocked up path then touch the fire and drag it to the beginning of the black line this should make it blow up

walk through and tern left keep on going until you can climb up the raised platform

walk up it until you can see a box walk up to it and touch it, it should open and a poster should pop out then carry on looking around for boxes that look similar.
