Card # J-19; Casey Jr. and the Storybook Land canal boats. The shore looks so barren, but the miniature scenes (such as Toad Hall) have been put in place, so at least there is something to look at.
Card # J-20 has this fantastic image of Monstro, it's one of my favorites. Years ago one of these cards sold for almost $200 on ebay... but I'll bet you can find one for a lot less today.
J-21 features the Mark Twain, and a Frontierland that looks surprisingly vast. Vesey Walker and the Disneyland Band crash the party over on the Twain's bow.
And lastly, card # J-22, with Main Street Station, the E.P. Ripley, and lots and lots of attraction posters! I'm wondering if the photographer stood on top of a large truck to get this elevated view?
