Jem Star Stage # 4100 It was a mixture of a few different toys- most obviously it's a real cassette player, made to look like an instrument for a child to play with.  Then it opened up and became either Jem's stage or Jerrica's office, PLUS under the floor you could store all your extra Jem goodies!  The Star Stage could be hooked up to the Backstager and was to be used with the Video Madness playsets (the backdrops fit perfectly over the back of the stage).    Known Variations Comments and Fun Facts Sold Both years. Compare Star Stage prototype photos, box art, cartoon form, comic book form and many other incarnations. The back of the box always says what is contained with the playset.  The bold words in my descriptions are what Hasbro themselves stated came with the Jem Star Stage;  Contains; Star Stage case with working cassette player, adjustable shoulder strap, 3 doll stands, and 1 Jem logotype, folding office backdrop with moving TV image, label sheet and instructions.  Pretend accessories include; 6 lightning bolts and two speakers, 3 microphones with bases, 8 spotlights, and 4 spotlight clamps, file cabinet and telephone, coffee cup, desk and chair.

3 doll stands (I believe just the "leg holder" part, they fit into the pink floor.

Jem logotype; quite large, about 5" wide, on white plastic, has a plastic clip in the back to attach it to the stage "wall"/lid.

folding office backdrop with moving TV image See the side flap. Thanks to Pete B for the TV image scan!

6 lightning bolts; two of each colour; hot pink, orange and yellow.  They fit into grooves on the stage wall (inside lid)

two speakers; KJem came with green speakers of the same mold.

3 microphones; one of each; orange, hot pink and green.

bases (for the microphones), one of each; green, orange and hot pink.

8 spotlights, and 4 spotlight clamps; (shown assembled); there are silver squares where the "lights" would be so they do actually reflect light.

file cabinet; rather generic looking, does not open drawers or anything, it's hollow in the back.

telephone; This is the phone I got with my boxed Star Stage, it may not necessarily be the correct one...

coffee cup;  Thanks to Eliza for the picture!

desk; comes in three parts; table top and two sets of white legs.

chair.  Came in three pieces; the middle seat, the right leg and the left leg.**

Hasbro neglected to mention;
 

1plastic side flap;  it must be replaced and removed when using the Star Stage as a stage and not an "air keyboard"

"office" side flap (made of thin cardboard)

I'll give more details in the future as it's really not terribly interesting to me!
