This is what the web is for. Basic Hip Digital Oddio is converting classic childrens' records from the 1940's and 50's to from paper and vinyl to jpeg and mp3. Each week this year, they upload another sweet, seriously old-school multimedia title.
There are Disney titles (I'm downloading "Songs from the South for Children" as I type this), fairy tales, cowboy music, all kinds of old-fashioned goodness. (Well, not that good if you still count Little Black Sambo as an potent symbol of racial discrimination, but des heer tar baby don't noes nuffin' 'bout dat. gun let her multi-racial frenz larn some sense innuh her 'bout folks' skin don't mean nuffin' jes de contents uh dey character. ahem.)
