This was seen in yesterday's post. A Brief History Of Northwest Coast Design is by Luke Parnell.
The accompanying panel tells a bit about it, and identifies the artifact in a display case following it.
In the background of the above shot one sees a portion of this work. This is it in full. Inuit artist Jessie Oonark created this drawing in 1966-69, titled When The Days Are Long And The Sun Shines Into The Night.
Stepping out of this room and through a side door takes us into one of the two interior courtyards of the National Gallery. This one has a garden that is a visual delight.
