Poster & Gasoline

I can't figure out what I'm doing wrong, but I can't find/get a poster to rip away to show the hole in the fence. Is it the poster with the man pasting it up? I've tried that one as well as all the others. I've checked a walk-through to make sure I've completed all the previous steps--ie/ have the gas can, talked to Malka, the brothers, been to Cabaret, etc. Would appreciate any and all help!

Have you been to the fence where you have spoken to the brothers through a hole in the door? If you move along the fence (left of the hole) until you can't go any further you'll find the poster. You'll see that there are two planks missing. You have to move the cursor at the top of the poster, there the cursor changes and you can rip off the poster. Hope this works for you.
