Where to post an interesting book cover?

Hi all,
I have a classic book with an (what I think is) interesting cover that I'd like to share. r/books doesn't allow image posts and r/BookCovers appears to be for creating or requesting book covers.
Does anyone know of an appropriate subreddit for interesting book covers, besides something generic like r/pics?
Hope this is allowed here, I didn't see anything about it in the sidebar but I understand if this isn't considered relevant to the sub.
thanks in advance and have a lovely bookish day!
