A branded calendar that leaves the desk has not been rejected on taste. It lost a competition for surface area that nobody thought to enter it in.
Desk space is the scarce resource
A laptop, a monitor, a notebook and a mug have already taken most of it.
Anything that arrives afterwards has to justify the footprint it claims.
One month for a large rectangle is a poor trade
An easel shows the same month using almost no surface at all.
A pad takes far more, and repays it only by being the writing surface.
The other exit is falling over
A creased fold relaxes, the angle opens, and the calendar walks forward.
Once it has gone over twice, it goes in a drawer.
And the quiet one: it cannot be read
Approved flat on a screen, then seen at thirty degrees on a desk.
Type that was fine in the proof is cramped in use, so people stop looking.
