Lost Letters

A sign for a day nursery is missing some letters.

Lost letters point to a problem of maintenance.

Same for a Toronto City building. First word 'oronto' second word is gone.

The effect is immediate because meaning is lost.

A church street sign is incomprehensible.

The reader must work hard to fill in the blanks.

Letters have fallen to the bottom of the enclosed frame.

How hard do your readers work?
