These are the cartoons I spoke about in class last week.
Beautifully drawn using rotoscoping (the process of tracing photos of actual actors to capture movement) with stunning composition and coloring-- these have inspired GENERATIONS of comic book artists. Check out the sample above.
If you're interested in getting a set-- get the official set from Warner Bros which is from the best possible film sources-- beware cheaper sets because these are in the public domain and can be released by any video outfit making a lot of inferior copies out there.
SUPERMAN CARTOONS ON AMAZON -- GET THIS SET.
Note: these might be out of stock from Amazon-- you can search eBay for the same set, I just got one for $10 plus shipping. There are also third party sellers on Amazon that have these.
Or you can just watch them free on YouTube-- they will go a long way towards helping your work.
