The quality of the fabric is more important than the age. If it was well stored and cared for, being "vintage" doesn't matter. I do recognize a few of the vintage fabrics. For example, one of the pink florals is in the vintage quilt wrapped around me right now! My great grandmother made it. I also recognize other prints from quilts my great grandmother and grandmother made, and prints I've seen in the local Quilt Shop that obviously aren't vintage. But don't put me to the test! I'd hate to be graded on being right on this! You're only getting my best guess.
Bet your quilt will be fantastic!
