Newfoundland 11-23 Images page 2

This is the first time that I have tried to upload images. I scanned them at 1200dpi, so I hope they are Ok for a a fairly close scrutiny. 

I obtained these 6 stamps more then 25 years ago, probably at an auction in Ottawa, but otherwise the details are unclear.

I have had a look at images of forgeries for these stamps and they look ok, but this is my first go at this. I know there is a pdf circular that is available but I can not seem to lay my hands on it now. 

I have some duplicates: 2 of 11A, an uncut pair of 19 ( Suspect it is red-brown) as well as 1 of #20.

Any comments re authenticity are appreciated. Also if there are any suggestions re adding album pages.


Thanks,

John
