I'm going to guess... and I have zero experience here. I want to say that based on some of the larger fabric designs I'd say late 60's. My neighbor was a seamstress and she made herself clothes with "modern" florals like that. Two of the smaller prints look similar to what I bought to make a quilt back around 1968. But then, looking at the last picture, the tiny turquoise and brown flowers separated by the little stars, have the distinct 50's look to it. Next to it, the blue check with the pink/yellow/pink dots has the 30's look. Bottom line, this is a gorgeous quilt in beautiful shape with a selection of fabric that Is uniquely created with fabrics that may have spanned a couple decades. It says to me that someone lovingly put it together from grandma's sewing basket, the calico counter at the department store and maybe her closet.
