Trekkie or not, surely there was no kid on the planet or in the federation that would have been seen dead wearing this monstrosity. Produced in 1976, by the Azrak-Hamway Incorporated (AHI). The company acquired the Remco toy company in 1974, after Remco filed for bankruptcy in 1971. As part of the acquisition AHI got the licensing rights to Star Trek. So in the 1970s they churned out a number of Star Trek tie-in toys. Some better than others, and some closer to replicas of items found on the TV series than others. The one item they brought out that bore no relation to Star Trek, was the "Official Star Trek Helmet", that has since become known as the Spock Helmet. Even though the company produced them with decals, so that kids could customise them with whichever character they wished.
The "Space Fun Helmet" was simply an insane piece of weird design. If they'd have left it at a helmet with a visor, then it would have likely disappeared into bland toy history. But the addition of the two antennas and what essentially was an emergency services flashing light on-top. That was referred to as a, “flashing light emitter with pulsing sonic sound.”
In addition to the helmet, AHI produced a Star Trek utility belt, that allowed for the carrying of the enclosed equipment, a phaser, a communicator and a tricorder. In 1975 they also produced a phaser, the earliest electronic phaser toys. The gun isn’t what you’d call an exacting replica of the screen-used props, with its bulky size and the Gold Key-inspired“Star Trek” logo emblazoned on its side, but what the Phaser Gun loses in accuracy it makes up for in fun. The phaser emits a "Realistic Phaser Sound" and a light shines from the front when the trigger is pressed.
While many of the AHI and Remco products released in the 60’s and 70’s are sometimes criticized for their cheap quality and wild inaccuracies, they still hold an important place in the history of Star Trek toys. As some of the earliest tie-in items from the franchise, they really are the stepping stones on Star Trek’s journey to becoming one of the most-heavily licensed properties in television history.
The Official Star Trek Helmet, has even gained infamy in its very own meme, referred to as "Spock's Helmet". Which involved photoshopping the helmet onto old pictures of Spock from the TV show and movies. Even Spock from the new Star Trek reboot franchise.
