I don't do a lot of applique, but I am making a 1930's reproduction quilt for my grandmother. I've been working on this thing for 2 years because it's a postage stamp quilt with quite a few reproduction fabrics.
I know that some of the Better Homes and Garden's quilt books have some nice vintage applique patterns. I own one of those books, but have checked out others from my local library.
As far as applique patterns, I did a search and came up with these:
