Sign

It was a quiet day, a mixture of tidying up after yesterday's excesses and lying on the sofa (after our unexpected overnight guests had vacated it!).

We strolled up to the bottle bank to dispose of the evidence and I noticed this sign. I think it should say "Leith Primary School", but someone's been erasing the letters. Is it meant to be Prima raised to the power e? Or is it indicating the whereabouts of high quality recreational drugs? I think I need another little lie down...
