Browsing an auction catalogue I saw a strip of stamps with OBRAZETS in blue. The stamps were rouble value Denikins. I show the strip below. Now, in twenty years I have never seen Specimen overprints on Denikins and I didn't know they existed. So I was a bit suspicious of this strip. Then, in the same catalogue, I noticed some Soviet strips with OBRAZETS overprints, though the colours seemed a bit odd. See below.
Then I noticed something that these strips have in common and which I have never noticed when looking at genuine OBRAZETS strips.
None of these strips has the overprint perfectly horizontal. They are all at a small angle, up or down. This makes me suspicious. First, that they all have this feature. Second, that normally such overprints are applied with great care. And, third, I can easily imagine someone feeding strips into a printer and finding it difficult to keep them exactly straight to take the digital overprint.
As a result of thinking like this, I won't be bidding for any of these strips.
