They are the "sock" style that pull over frames that are 8 feet tall and 4 feet wide.
Two of them are technology related, one sided and independent of each other.
The other two are from our "Shipwrecked" show and are two-sided. One side has a separate ship on each, then when you turn them, they go together to make one large, wrecked ship.
All four are in very good condition.
Price is negotiable.
