The Golden Ratio - Fibonacci Spiral Postcard
In mathematics, two quantities are in the golden ratio if their ratio is the same as the ratio of their sum to the larger of the two quantities. In its algebraic expression, the Greek letter phi represents the golden ratio. The golden ratio is also called the golden mean or golden section.

I had never seen these classic science fiction images and most of my friends have not seen them either. They are like little treasures! Amazing quality and fun to send people!

I joined Postcrossing a few months ago and wanted postcards to represent my state well. I found them on Zazzle. I purchased numerous cards and was impressed with all of them. Excellent! The colors are beautiful. The cards have the exact look I wanted. I couldn't be happier.
