Callcards with reverse printed upside down
I'm just wondering if people have come across many examples of callcards with the reverse accidentally printed upside down? I have 1 example myself, it is Callcard #1162 The Examiner. Unfortunately it is not in great condition but obviously still delighted to have as I've never come across another example of it. :)
Very nice Richard! Don't have any such error cards myself unfortunately. Interestingly though there were two Callcards which were released including a general one with upsidedown printing.
The 1228 Use us Today "Learning on the Internet" ODS version and of course 1230 Telecom Eireann Blank Promotion Card. I always wondered why the mistake for 1228 happened and was accepted. I guess because the rear of the card didn't contain any horizontally aligned text it did not really matter in this instance.
