Oh, now that's cool! So glad you found this treasure of vintage patterns. I hope you're able to use some of them (and translate the patterns without any problems). Then as you're knitting, you can think about your grandmother making that very same object!
I have my now-deceased grandmother's mixer--an old handheld one that is kinda beat up and ugly, but every time I use it, I think of my little grandmother making cakes. We have a shiny new KitchenAid mixer, but I always reach for the old grubby one. There's just something about using things from the previous generation that is special (at least I think so)!
Enjoy your pattern booklet!
