Urdhva-Pundram explained via 13 pictures (the illustrations from «HamsaPriya» magazine of Shree Ramanuja-Sampradaya)
There was a truly perfect article about Urdhva-Pundram in «HamsaPriya» Sri Vaishnava magazine, see this pdf-scan on archive.org, page 21 and further — https://archive.org/details/hamsa-priya-vol-1-issue-6-shree-ramanuja-sampradaya-magazine-vaishnavism.
I have processed all the images from this article via GIMP today — added more light filters, paper overlays, ornamental frames and so on. Below all the 13 illustrations — they are based on «Panniru Namam» by Shree Vedanta Desika.
