About This Design
Icosahedron With Golden Rectangles (Geometry) Postcard
Like icosahedrons? Know about golden rectangles? Showcase the icosahedron, a regular polyhedron with 20 identical equilateral triangular faces, 30 edges and 12 vertices, with any of these geometry gifts. The icosahedron is one of five Platonic solids and includes golden rectangles (i.e., a rectangle whose side lengths are in the golden ratio, one-to-phi, or approximately 1:1.618). Mathematicians know that a distinctive feature of this shape is that when a square section is removed, the remainder is another golden rectangle -- one with the same proportions as the first. Educational geometric fun for all!

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.
