There are several new bell toys that resemble vintage litho paper over wood originals from the late 1920s-1950s era. The new pieces have painted wood wheels, wooden bodies covered by paper and bells that ring when the toys are pulled.
Look for the word "Schylling" on the paper. Schylling specializes in nostalgic toys. The company was started in the mid 1970s. Any toy with that name cannot be older than 35 years at most.
