There are a lot of good & interesting items. First flight covers, FDCs, etc. There a couple of Gandhi postmark covers, Swiss FDCs etc.
Also listed are some early Air India covers.
I have listed 10 scarce India International Balloon Mela 1985 flown covers. Only 100 covers of each were flown on the balloons taking part in the mela. I have never seen these listed on ebay before. All the covers have details of the balloon, pilot, landing point.
