Where to find fonts?

I am doing a personal project that requires some mixture of images and text. I’ve gotten the images that I want and I know what are the text I want to put in. The only thing missing is the exact fonts that I want to use on the text. I especially like fonts like those postcard printing but don’t know where to find it. Anyone has any idea? Hopefully I can find them free for download. I’ll go search around the web for some free font download sites and see if I can come across what I want
