Hi everyone!
It's been a long time since I've posted on the forums here. Took quite a long time off from collecting but am now back into it and came across a bizarre block of #1203 Dag Hammarskjöld stamps. In the picture below the first block has the yellow plate number
27275 printed upside down or inverted.
While the block below has the yellow plate number
27282 printed the right way.
Has anyone else seen this? Is this normal or some sort of an EFO?
Thanks for your help everyone!
