Some of these items are semi-rare and tricky to find cheaply on ebay.
Sigmund and the Sea Monsters is a Sid & Marty Croft production that I recall watching on TV and loving during my early childhood years. It should be a real trip down memory lane for folks like me who grew up in the 70s, and, for everyone else, an interesting and highly entertaining look at the weird and wonderful style of kids' TV shows during the 60s and 70s.
The Voltron set includes 3 discs worth of episodes and is Like New, with shrink removed. In fact, I'm not sure that this set was ever even watched once. I think I might have popped in one episode on one occasion, only to discover that my kids weren't into it.
The other items range from Very Good (Tom & Jerry, Sigmund; a Half Price Books stickers is affixed to the Sigmund case, to Good (Ewoks).
The Ewoks disc is a former rental from Blockbuster Video (remember those days??) and it has some faded cover art and a sticker on the case.
Some of the discs may have very light scuffs, scratches, or fingerprints that do not affect play.
These discs played 100% fine without skips or freezes on my home DVD player. They are all region 1 discs.
I store all of my movies indoors in a smoke-free, climate-controlled environment, on a shelf with other discs.
If you have any questions, please feel free to ask. Thanks for looking!
