Quite a bit; collectors are waiting and wishing.
The OP asked about the 𝒐𝒍𝒅 Looney Tunes cartoons, and most everything mentioned on this thread isn't that. Characters like Porky, Daffy, Bugs, Elmer, etc, are from what could be called the Warner 𝑐𝑙𝑎𝑠𝑠𝑖𝑐 era, when they were at their theatrical height. But Yosimite Sam, Pepe Le Pew, Tweety, Granny, Sylvester, Marc Anthony & Pussyfoot, Bert & Huey, Marvin the Martian, Taz, Witch Hazel - these are all relative latecomers to the repertoire. Speedy Gonzales, the Coyote & the Roadrunner, are from close to the end. By the early sixties, it was over. And while 'Animaniacs' and 'Tiny Toons' may be nostalgic to some millennials here, they're not really part of what this thread is about.
The old Warner cartoons (both Looney Tunes and Merrie Melodies) are mostly about non-famous-name characters, like a pig who winds up being force-fed by a mad scientist's machine (𝐏𝐢𝐠𝐬 𝐢𝐬 𝐏𝐢𝐠𝐬, 1937), three squirrels arguing about "𝑤ℎ𝑜𝑜𝑜'𝑠 gonna play Robin Hood?" (𝐑𝐨𝐛𝐢𝐧 𝐇𝐨𝐨𝐝 𝐌𝐚𝐤𝐞𝐬 𝐆𝐨𝐨𝐝, 1939), Old King Cole marrying the Woman in the Shoe (𝐓𝐡𝐞 𝐌𝐞𝐫𝐫𝐲 𝐎𝐥𝐝 𝐒𝐨𝐮𝐥, 1935), a teen-aged mouse who wants to become a boxer (𝐂𝐨𝐮𝐧𝐭𝐫𝐲 𝐌𝐨𝐮𝐬𝐞, 1935), and a pair of mischievous bear cubs who get into some corn liquor, release the handbrake on a wagon, and go careening down the mountainside (𝐈 𝐖𝐚𝐧𝐧𝐚 𝐏𝐥𝐚𝐲 𝐇𝐨𝐮𝐬𝐞, 1936). There's just too many great cartoons to single out. There's some repeating characters, like Peter Rabbit (𝐂𝐨𝐮𝐧𝐭𝐫𝐲 𝐁𝐨𝐲 and 𝐌𝐲 𝐆𝐫𝐞𝐞𝐧 𝐅𝐞𝐝𝐨𝐫𝐚, 1935), Egghead, 'Two Curious Puppies,' and Sniffles the Mouse; and lots of celebrity parodies - W.C. Fields, Humphrey Bogart, Jack Benny, Johnny Weissmuller, Katharine Hepburn, etc. These are the truly great cartoons, from a time before the point when watching a Warner cartoon would mean only a small handful of repeating characters.
