A huge collection of postal cancellations on Irish stamps

A huge collection of postal cancellations on Irish stamps. The range varies from Irish first issues till stamps from 1990s.
Some stamps are with defects as they taken for cancel marks purpose. The collection is presented on various stock-cards.
One off item. It took me a lot to built such collection.

I am starting to sell my own collection and inventory. Being a collector for 50 years, I don't have a health and vision to continue. The most of the stamps are 'back of book' items what means that the best stamps are usually placed at the back of stock-books/albums. I need some time to place them in albums to be prepared for photos.
I make the photos of all stamps you will get. Hopefully it happens every week.
Or to be continued...

The photos of all stamps provided,
please examine the scans before you bid.

No swaps offers Please!

I am only offering a collection from D1 (Croke Park area).
