Vntg Mid Century Modern Cosco Child Booster Seat Chair

Excellent vintage 1970's Cosco avacado green childs booster seat or chair.  Measures 12 1/2" tall from floor to top of back, 13 1/2" from side to side at very front and 9" from back of vinyl to front of seat.  Only has two minor condition issues, first being the surface rust on the hinges at bottom only minor and probably would scrub off, joints still move freely, this rust looks much worse in these pictures than it actually is-please keep in mind this is a close up until I started taking the pictures I didn't even notice the rust.  Second issue is a crack on the front right edge.  Cracked on top but does not go through the chair as shown in pictures 7 and 8.  Also has minor scratches and scrapes all totally consistent with age and use, none detracting and no rips, tears, holes, stains or repairs.  Please study all photographs closely as they are considered a large part of this description.  Great, solid little seat with two adjustments on bottom, perfect for that Mid Century Modern Brat!
