Overprint 'CANCELLED'

[Interstellar]

Hi all

I have a 1/2d Orange QEII postage stamp overprinted 'CANCELLED' Cannot find this listed anywhere. Do you think somebody has just printed the O/P themselves?

Any help

Can't help with that one. You wil need a specialised catalogue e.g. SG volume 3
(it may be available at your library.)
Failing that ask one of the main dealers e.g. BB Stamps

That's not an overprint, but a cancellation (since it says so). Perhaps one for fiscal and/or accounting purposes.
