Box is undamaged, aside from minor wear from age.  Cello is intact.   Corners, etc. are intact.   Lost in Space labeling is quite legible.

A generic astronaut mask is what came originally with this costume, and it is present with original elastic and no breaks.  

The rayon material in these costumes tends to darken with age, and this one is no exception - please see pictures.   There is some fraying of the red tie at the collar and at the extremities of the sleeves and pants.   Not bad though for a sixty year-old item!

This is a "Must-have" for the serious Lost in Space collector.
