Sweden. Military cover Facit Mu2 , The Swedish Åland Demolition Detachement 1919. A nice military letter Mu 2 machine-cancelled "STOCKHOLM 1" 23.8.19 on nice mounted page to a Swedish 2nd Lieutenant at the Swedish Detachement at Åland. This letter (unused) have most probably been folded due to be sent from the addresse in a letter to the sender to be used back to him for free instead of exchange by coupon, because the enclosed letter content is not folded at the same way. Very rare to find with content that can prove this handling. Good quality but slightly worn. Exhibition item!
