I found a great video compilation Imai Thunderbirds model kit commercials from the 60s. Imai produced the majority of Gerry Anderson/supermarionation related model kits for Japanese fans in the 60s. These commercials are a lot of fun to watch and even feature some stop motion animation. Be advised that there is a 1 minute and 28 second introduction in Japanese before the fun starts. It's worth watching. Thank you Youtube! I've also included a sampling of Imai Thunderbirds box art created by legendary illustrator Shigeru Komatsuzaki. Enjoy!
