Here is a very nifty five inch doll of Ernie made by Knickerbocker. The shoes are attached as the doll's feet but the shirt and pants are removable. These dolls don't seem to be as common as the rag dolls (shown on the "Sesame Street 1969-1979" page). The box has a copyright date of 1981.
This is the back of the box for the above Ernie doll. It shows the other dolls available in the set, Big Bird, Cookie Monster (with chef hat..it didn't show up in my photo), Bert and Ernie.
Hasbro began to make Sesame Street toys in the 1980s. One of my favourite collections from Habro are the Sesame Street metal cars. Here is a photo showing 21 different vehicles, and there are still several more in the collection. Missing from this picture is Herry Monster's Gym Mobile, Grover's Airplane, Grover's Speedster (a silver spaceship), Grover's Helicopter, Ernie's Helicopter, Oscar's Trash Can Roadster (a trash can shaped car), and Bert's Snowplow. There are 28 vehicles in the collection that I know of.
Tara Toys made two sets of Finger Puppets in the 1980s. The back row in the above picture is the second series, only Oscar is missing (he was holding Slimey the worm). The first series included the same six characters but they weren't holding anything. Applause made the next series of finger puppets in the late 1980s or early 1990s, shown above in the front row. From L to R: The Count, Cookie Monster in Western outfit, Betty Lou, Elmo, and Alice Shuffleupagus. For the latter three, this is the first time a finger puppet was made of the character. Cookie Monster is from a Western themed series that included Big Bird, Oscar, and Prarie Dawn. A third series based on a theme of different jobs, included Betty Lou as a Doctor, Ernie as a Fireman, and Big Bird as a Postman.
