The 1988 Valise came out in the new Burgundy Box with the beige paper band.
This box was used from 1988 to 1991. The Heart Code is SWAL.
The Pamphlet has a 1988 copyright.
The Handles have slight differences. The 1988 handle protrudes up from the case. The Mattel American girl handle is very flat and close to the case.
The Rivets are different on all three. Plus I have seen others that use a rivet staple to hold on the handle.
The textures are different on all three. The clasps were the same on the Pleasant Company versions. The Mattel American Girl version has a different clasp.
