My Congratulations to all 6 winners from India.
I am not sure whether there was any GANDHI stamp collection exhibit in PhilaKorea 2014.
Not sure whether there is any interest in Gandhi stamps collection as no winner
Looking to past exhibits I can understand majority of the Gandhi stamp philatelic material is nothing but BOGUS or forgery so it does not make sense to participate in exhibition where philatelic judges now have enough information to look on the web and think about it before they decide to disqualify the entree.!
Still you will see Gandhi exhibit during some events or speeches because no one will question about their collection as it is only to gain popularity.
In USA I don't even see any Gandhi stamp Exhibit (click following link to see) in Westpex 2014 one of the biggest stamp exhibition even though there are high price Gandhi stamp seller on eBay are from San Francisco, Santa Clara, Los Altos or Sunnyvale.
So not sure what's going in Gandhi Stamp Collector.?
Gandhi Stamps collection is DEAD or Collectors are afraid about their collection because of following BOGUS items in their collection which they proudly display one time.!!
Following are some of the BOGUS material you will see in past exhibition as well in philatelic handbooks.
1) Rare Specimen stamps in Leather folder
3) 1969 Fiji, Luxembourg, Burma, Czech Republic Commemorative cancel or Special cancellation (wide varieties available)
4) Gandhi SERVICE BOGUS overprint stamp and FORGED or BOGUS rubber stamp of Governor General. )Some of this have Expert Certificate.!!)
