Creator Review
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.
