Who are you Pat Prichard?

Am I not the biggest nerd for wanting to check out this book: Hanky Panky: An Intimate History of the Handkerchief by Helen Gustafson? I stumbled upon these handkerchiefs by Pat Prichard and just think they are the loveliest. And then wanting to learn more about Pat Prichard - I did some hardcore research and googled. I found nothing about her on the internet (I imagine the artist to be a woman) though a lot on other hanky designers like Tammis Keefe. So the prettiness of these hankies has me curious (and greedy, I hate to admit)...
