So, I’m answering this questions:
1. The images with error in word «КолкотоваЯ» (a superfluous letter «Я» on the end) have been printed in a trial variant only on a poster (dense) paper.
The finish variant (corrected) has been printed on other paper (selfadhesive paper)
Therefore there are the color distinctions between the trial and the basic issue variants.
2. The block has been printed without an error in word «КолкотоваЯ». Therefore there are any trial variants in it.
It is said that there is an inscription error on the stamps and pictures are displayed. I have two questions:
1. I see big color changes between the original error type and the "repaired" type. The original stamps are violet and brown and the fixed stamps are olive green and grey. Is this actually correct, or is this just a problem with the image scanning?
2. It is not clear if the inscription error was also present on the souvenir sheet (block). Is this correct? Did the block also have this error?
If anyone has a good/big scan of the block with the error, please can I get a copy.
