This week I received the 1st/4th of RotK, so I didn't order the 'original' edition of Seinte Iuliene after all. Perhaps I will buy it too, but I'm still doubting. I found it for approx. £55 with original cover - not rebound like the one I mentioned and showed earlier in this thread - but it's a lot of money to me...
A photo of RotK is coming, but it's not that special to you guys, I think. (For me it is, as it is my first LotR 1st edition so I'm quite proud of it.)

I would be proud as well. I recently found later printings of first editions of the ROTK and TTT online, and am anxiously awaiting their arrival (they will be the only first editions in my collection).

Here's a photo of the book (although not really necessary as I already have posted a photo by the previous owner)

As already mentioned (and you see from the picture), I believe that this is the only first edition LOTR edition with the impression details on the dust jacket spine. An unusual copy.

I have the 2nd and 3rd impressions of ROTK and both have the impression number on the spine as well. See below...

Thanks, I did not know that the first impression dust-wrapper does not have the impression number on the dust-jacket spine.

Does anyone know which impression they stopped putting the impression number on the spine?

Yes - it was the fourth impression (May 1958)

Well I picked up a 1982 Deluxe LOTR India paper edition for £54.50 delivered today. Book in mint condition, box very good - can't wait as I really like the look of this book - it also came out in the year my wife was born which for some reason makes it feel special haha.
