Make Marketing Legible.
Iceland have a claim worth promoting.
Although perceived as a low-end purveyor of frozen goods, they apparently produce the best mince pies in the mass market. So I have no problem with the claim, but in the West we read from left to right and horizontally. Not vertically.
What you see first is a list of their competittors. No comparison, just their names. I take Selfridges away from this ad as much as I do Iceland.
If you look longer you might eventually discern the Iceland name, but why make it so difficult? They spent a lot of time coming up with the word puzzle, but didn't think to flip the diagram. That would leave the competitors' names written vertically and Iceland highlighted as a horizontal name.
It would be easier to read and you'd have Iceland riding high at the top of the image. Why didn't anyone pick this up? What goes on in creative sign-offs? Given the recent Dove debacles, it's increasingly hard to comprehend.
