Hairline In My Unitrade 138

The first pic is a VF/NH imperforated block of 8, from plate 128. The black arrow points to a hairline between the stamps in the 3rd column.

The second pic is a close-up of this hairline, which is slightly running into the bottom stamp.

The difference in shade is due to the use of different hadware for the pictures.

Has this mark been reported before? Any explanation for the presence of this line?

Major1044, I can not answer any of your questions, but that is a great variety! However, it does not look like a hairline crack to me, but more like an etching scratch. No less better to have found though,

Agreed. I don't know the correct terminology, but it is probably some type of engraver's slip or a scratch from some other tool. A beautiful example, by the way.

Thanks! Your comments are much appreciated. I will add your information in my stamp album.

Agreed

Two examples of so-called Engraver's Slip on the 3c Small Queen.

Impressive!

In particular, your bottom stamp jimjung.

Do engraver's slips add significant value to stamps?
