Hi @billl14480416, you are right, looks like Penumbra is no longer offered through Adobe fonts. Apparently, it was associated with Adobe at some point in the past, as it's listed here for sale under Adobe fonts:
https://store.typenetwork.com/foundry/adobe/series/penumbra.
Also, I note that the site is selling some of the same Adobe fonts that are now offered via Adobe subscription:
https://www.myfonts.com/collections/adobe-foundry.
@Molly Doane is that allowed? Are they an authorized distributor of Adobe fonts? Can you tell us if Penumbra could be offered again via subscription? Thanks!
