This is a tiny drawing which I am working on. This is Zacharay Smith, Don, Will, and the Alien from His Majesty Smith. The alien is one of the coolest aliens in the series. My drawing doesn't do him justice.
In Lost in Space a lot happened between Reluctant Stowaway and Island in the Sky. They barely made it to the planet. Here Maureen is still in her silver flight suit. Rather, she looks like Irene Dunne here, not June Lockhart.
