The links for this listing both go to antique pattern library, a great, but huge resource. Once there I searched for DMC Irish crochet and came up w the publication itself. As a very old, out of print free booklet, the most direct link to the pattern is likely the one for the entire DMC booklet.

This pattern appears on the right half of page 18. Conveniently this is page 18 for both the printed book and the PDF file.
