Also not sure whether this was flown by balloon to Chicago to Ireland?
Also Ballymahon 2010 (40th Anniversary) was from 19-24 September and this cover was mailed on July 31 2010. !!
Also not sure which balloon it was flown by out of 44.
Lot of things to look in to this FFC to consider as GENUINE !!
Following FFC only has 44 cents stamps.!!
Not sure why this has stamp of USA as this cover is flown from Korea to Hawaii on 12-14 January 2011. It has already stamps from Korea.
As per USPS rates even postcard or letter(cover) required 98 cents for International postage stamps. so both cover postage stamps does not make sense.
I think USA Gandhi stamp is on cover, only to sell this cover to Gandhi Collectors.!! as no Gandhi stamp from South Korea.!!
My blog post also look colorful.!!
