Indian Princely States - [NEW] Indian Stamp

This is a set of 4 commemorative stamps based on the erstwhile Pincely states of India, namely : Indore (Holkar) , Bamra , Sirmoor and Cochin.  I simply loved the design of the stamps and the way they are over printed.  Also, the way colors are used to showcase the heritage is notable.

A Princely State (also called Native State or Indian State) was a nominally sovereign[1] entity of the Empire of India which was not administered by the British, but rather by an Indian ruler, while the British Crown had suzerainty or paramountcy, completely controlled the state's external relations and exercised a degree of indirect rule over its internal affairs, varying in scope from one state to another. 

Out of the 560+ princely states, I hear that only 40 odd had postal systems and issued stamps.
More on Princely States of India can be read here and here.

I will be getting the miniature sheet of this soon, as i am pretty sure this would be a collector's masterpiece in the near future.
