I have noticed a small flaw in OF.1.62. It is circled in this scan from printing 4:
The final image includes two used copies from my collection. Printing 4 position 30 shows the flaw and also the brown spot in the large 6. Printing 7 position 15 also has the flaw.
Comments in English or Danish are most welcome.
It is also present in printing 6 and 9:
Based on this I looked for this flaw in printing 5 and believe I found it in position 81:
It is interesting that in print 4 there is a brown spot in the large 6; this is also seen in position 81 in printing 5 but is not seen in printing 6. There is also a hint of the white spot of OF.1.62 in printing 5, indicated with an arrow.
