About This Design

The Golden Ratio - Fibonacci Spiral Postcard

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. You may edit or delete the title.

Exactly what I wanted, it is very difficult to acquire Vintage Australiana items. I am so please that I ordered 8 I will be using them for my scrap booking and Junk Journaling. Gorgeous, Zazzle produced and delivered exactly what I wanted.

Way better quality than I ever expected. I love the colours, font and quality of the card. I'm so pleased I found Zazzle as it is near impossible to purchase Vintage or Retro Australian memorabilia online. I chose this design when I purchased them. They are perfect for my projects. I was very specific about what I wanted. I know where to come now when I need to order similar items.

Perfect for the occasion I was using it for. I was able to delete the lines so I could put in more wording. Had an envelope so the address side wasn't necessary. Print quality and paper quality lovely.
