Hi everyone,
Pasi, OH3IW, replied promptly to my inquiry regarding the printing of the island name on the cards of OH2U/P, indicating that:
"My minor mistake was not to print the word 'island' after the island name - I failed to think of this enough as the word 'island' doesn't really belong to the name of this island.
The island name - Lilla Grñtholmen (Lilla Grotholmen) is printed both on the QSL front and on the label. The island was approved for EU-097 on 24 July 2002 by G3KMA - please refer to him or your checkpoint."
As such, the matter is solved. Thanks Pasi for the informative reply.
