I was surprised today to discover that a philatelic study of worldwide portrayal of COVID on officially issued postage stamps was just published online in, of all places, the Journal of the American Medical Association (JAMA). It appears to be a well-researched resource document for this topic, and includes images of all of the 68 issues (through December, 2020).
This link is classified as "open access," so hopefully all interested can access it without a JAMA subscription.
Mod fixed link.
