Vintage Spooky have a range of fun unlicenced items inspired by the 1979 Kenner ALIEN toy. The art style and details featured in these goodies clearly indicate the toy was the inspiration for these designs. So many features are replicated in them; just look at that wonderful tail!  Check it out with links to purchase direct from Vintage Spooky below.

You can find each of these fun items available on the Vintage Spooky Etsy store:
3 foot tall jointed die cut decoration.
T-shirt (Pre-order).
17 inch diecut decoration (almost the size of the original vintage toy).
6 inch Vinyl sticker.

I might have to get one or two of these things.
