Where's the eleven?

For a couple of weeks now I've been walking past this poster in the window of my local 7/11.

And every time I see it it bugs me.

No idea why. It just does.

Then this afternoon I realised what it was that was bugging me.

The missed opportunity.

Look at the headline - 11 flavours in 11 weeks.

Now why oh why didn't somebody think about using 2 slurpees in the ad to create a visual representation of the number 11?

Kind of obvious once you think about it.

Don't you think?
