I ran across some fragments of old magazines that used to belong to my grandmother. The scraps date back to about 1923 or earlier. The first is a picture of shamrock lace in honor of St. Patrick's Day, but unfortunately the page with the pattern on it is missing. The Antique Pattern Library is gradually adding old volumes including these old Needlecraft Magazines so it is worth looking at for old knitting and crochet patterns (http://www.antiquepatternlibrary.org/).
The second picture is an advertizement for a needlework magazine subscription from a 1919 booklet. I love the price, 25 cents for a whole year!
