In the past ten years, vintage greeting cards have become very collectible for their art, but I've only been collecting them for five years. My collection consists of a little over two thousand cards, but there are people out there who have thousands more. I share my collection of these great images with the whole world on my Flickr account. Here are just few of those cards to give you a sample of what is out there. And if you want to know the value of vintage greeting cards, you can find a few books on the Internet or at your local Barnes and Noble book store. The more unusual cards and cute animal cards sometimes bring the most money. So if you have an old scrapbook or box of cards from your mother, father or grandparents, think twice before you throw them away or use them as kindling for your next campfire.
