This is a set of Cook Islands 1935 stamps.  They are SG 118-121.  What's cool about these is that they are actually New Zealand Postal Fiscal Stamps, but they are Overprinted with "RAROTONGA" for use in the Cook Islands!

This is a lovely set!

These stamps are all Mint with Original Gum and in Very Fine condition.  They are valued at L250 in the Stanley Gibbons Catalogue!

This item is over $100 USD so I will be shipping it using Priority Mail in the US, and Registered Mail overseas.  This is to ensure that it reaches you in a safe and timely manner, and includes tracking!
