Good Housekeeping is sold out of all of the copies of this magazine. There is no way of getting this magazine issue or a copy of this pattern from them.
I have found eBay to be an excellent source for old patterns, if you know the issue search for it. You can also try tias.com, as they have tons of old magazines, categorized by name and topic. Good luck.
