Wall poster
Can anyone help me source that wall poster with a large number of helicopters in side on view. I think it is called "Helicopter identification" or something like it. It's big, maybe 140cm by 100cm. and starts off with the smallest in the top left and finishes with the big Russian jobs at the bottom.
It is published by Phillips Business Information Inc. in the USA but their web site has nothing about such pictures.
Many thanks
