1972-77 Definitives, Unitrade Listed Flaws Question.

Good afternoon all,
I recently purchased the 1998 edition of the Unitrade specialised catalogue. I have spent a fair bit of time going through my Canada collection to check all against the book, and have found a few nice listed flaws. I am now going through my duplicates as well.
However I am having difficulty with a few of the items detailed in the catalogue, due to not all flaws being illustrated.
The above series, 1972-77 definitives, on the values from 10c, has the following listed that don't make sense without an illustration.
15c 595vii 'blue tail' variety (I have figured out viii!)
50c 598iv 'broken C' variety - I have a candidate for this but mine has a white square under the first 'a' as well!
Can anyone show illustrations of these two flaws?
Any help would be much appreciated.
Regards
DavidR

This is one example of the blue tail, which is far to the right of the sheep. Others can be just off of the rump.


Even the 2021 Unitrade does not not have an example of the Broken C, so I can't help you with that one. I don't have one either.

Thanks very much BlackJag!

This old thread The 1972-1978 Caricature And Landscape Issue Of Canada has a lot of good information and might help you
in what you are looking for.

Thanks for that link lithographing. And a belated thanks to BrixtonChrome for such a detailed post in that thread. Very informative!

Yes stamps101 I agree with you about BrixtonChrome, too bad he hasn't
been posting anything on here for quite awhile.

Lithograving - that's great! Thanks very much.
