This 1950s Miniature Perambulator is supported by a suspension system much like a a full sized pram. When I purchased it from the owner she said she had used it to walk her dogs in it, and I bought it thus. Upon getting it back to the store I realized that it must have been for dolls. It's car-like appearance makes it seem like it was acquired directly from Stuart Little's estate. Constructed of extruded plastic, chrome plated metal, rubber and cardboard, it sports a satin lined mattress. It is in very good condition. SOLD.
