Postcards From The Edge

Posted by John Bailey on March 13, 2001

There are several movies with titles that aren't readily obvious, like "Catch22", "The Green Mile", ect, but I just saw "Postcards From The Edge" and can't figure out exactly what the title means or refers to. I looked it up on the web and found hundreds of references, some having nothing to do with postcards. Is this a known phrase that has some specific hidden meaning?
