How about a jazz EP? I’ve only found a handful of them so far, as they are a bit of an oddity, but I like them a lot and hope to acquire more.
This one has a great cover by David Stone Martin, which is probably the most collectible thing about it, but the music is good too, played by a trio of Benny Carter (as), Art Tatum (p), and Louis Bellson (dr). I have another no-bass trio LP, also on Clef (709), with Buddy Rich, Lionel Hampton, and again with Art Tatum. I prefer that LP, but this EP is a nice piece of jazz history with some great musicians.
