"Little Rural Riding Hood" (1949) is sort of the end of an era for Avery: it was his last cartoon with "Red," the sexy red-haired dancing girl he'd introduced in 1943's "Red Hot Riding Hood." In fact, the animation of Red in this cartoon is all recycled from an earlier cartoon, "Swing Shift Cinderella" (not available online), as Red's animator, Preston Blair, had left the studio the year before and no one else could animate the character the way Blair did. You can see, in the cartoon, a bit of a clash between Blair's Disney-trained style and the more streamlined, minimalist animation style of some of Avery's younger animators -- we're seeing a transition here from the rich, fluid animation of the '40s to the less elaborate '50s style.
"Little Rural Riding Hood" contains the single funniest line in any Avery cartoon, which occurs after the country wolf accidentally kisses a cow. (I don't know why it's funny; no analysis will help; but I do know that it brings down the house every time the cartoon is shown.) It also has a gag, involving the country wolf and a blanket, where he demonstrates that he is not "master of his domain"; this was also sort of the end of an era for Avery, who would tone down the sexual humour a bit in the '50s.
