PAM Advertising is not actually a Migros agency. But the idea of producing Migros bags with "Keep two M's apart." is nevertheless obvious. Topical and pointed without frills. Like "One M better" - only better. And by the way, the play on words conveys an important message that apparently many people still haven't understood. This is recalled with every purchase - some specialists are always going on a hiding to nothing. Of course, the problem does not only affect Migros, but also all other retailers and discounters that are (allowed to be) open these days.
So go, Migros - produce!
