From the classic Lost in Space TV series were these never released phone cards. Individual phone cards are indeed rare, but uncut
phone card sheets, are impossible to find. I have only seen one other set several years ago offered to me by Mike on the Lost in
Space Museum website. These cards were a promotional / demonstration sample only. For some reason, they never went any farther
than just samples? The Company that made these's "Frontier" decided not to market them after the 1998 remake film did not go over well. There were several Lost in Space Movie phone cards that were made and sold over sea's promoting the film.
