AFAIK quite a scarce item,
used label on mutilated piece
with "clockface" canceller pmk 1992
The Box Link labels were designed for business
services for PO Box holders ony. - PO Box to PO Box.
It was, at 30 cents per article 15 cents cheaper than the conventional mail rate. It did not turn out to be popular, and
did not last long.
Similar to ...
"Cross Town labels", providing a speedy across town package service for parcels weighing up to 25K. for $3.25. Again, this service was not used a lot, and the trial was never extended to other capitals.
