India Post, sometimes,  has issued stamps of same or similar pictures with little variation in colors or sizes on different themes, occasions or special events. The stamps look alike though with some little variation. The collectors with creativity have made covers with combination of such stamps respectively  cancelled on each Stamp. Such covers show the creative efforts of the philatelists.

Here on this official cover, stamps of President's Fleet Review, Visakhapatnam dated 12-2-2006 is combined with respective cancellations.
