Tip of the Iceberg.  What we see often is only a fractional part of what really is.  Global warming.  Root of the problem.  Postcard.

Great image with a profound statement. The truth in this statement can be understood on many different levels and applied to a wide variety of situations. This is only the tip of the iceberg. What is the root of the problem? Card published by Tushita in Germany. 

Often the Invisiblia of this world can be more important than the visible parts. This card illustrates that very well.

One thinks of the Titanic being sunk by hitting an iceberg. Certainly, it is true psychologically that the invisible history and wounds we have experienced have a major effect on how we think and act in the world, but it is also true in the physical world. Iceberg, ocean, mountain, sky. Powerful metaphor well illustrated. Perfect conversation starter in many situations.
