who's digging it?

I am imagining the moment where Mr Rosengren came up with the logo for his company. He and his friends (sweaty from the summer heat and with big beer bellies from all the beer during the years) are sitting in someones garden drinking beer. The macho guys with that special jargon joking around.

Then they get the brilliant idea. They have the tagline 'we dig also for you', Rosengren asphalt and paving, so hence they of course need a picture of a finger digging (picking) one's nose.

Bull's-eye!
