lol!!! saw this taxi not long ago only..... 
I have nothing to say to Stomper, really..... those are just
plainly the cut-out/unwanted advertisement stickers thats all, and
why make a fuss about it?
If the driver wants to decorate it, its still up to him/her
what..... I see nothing wrong with it.....
if the Stomper thinks its easy to decorate the bumper, i reackon
the Stomper to use that few pieces of left over
advertisement stickers to cover the rear bumper.....
