That elusive QANA Lebanon Stamp !!!!!

Looking for an ultra rare stamp? Well, here is a challenge for you..
In the 1990s Lebanon handed over its postal authorities to a private gepany, this gepany took the available stamps and overprinted them with a gold . While some stamps were availbale in numbers, others apparently were not !!! The result?? a set of 15 stamps, overprinted in a gold cross.
Among them was a small unimpressive green stamps called QANA, that stamp was used postally in less than a week, thus making it the rarest stamp in the history of Lebanon Philately !!

Good luck finding it .............
