One of my favorite collections is my vintage valentine collection. I started collecting them at least 15 years ago... I saw a bunch at an antique store for a quarter each and couldn't resist.
Since then I've found many at garage sales and estate sales. I once got 5 ziplock bags full at an estate sale. I refer to it fondly as the Brady Bunch estate sale. The house was like a time capsule from the 70's. I was in heaven.
I color copy them every year and use them to decorate my house. I will be doing some projects with them too.
Lots of love!
