Vintage 1977 Star Wars Darth Vader Ben Cooper Fun Poncho.
Back in the vintage days of Star Wars mania, kids would beg their parents for costumes; normally only during the Halloween season. However, costume maker Ben Cooper made three "costume - like" ponchos that children could wear any time of the year (well, as long as it was raining, that is) and feel like they were once more dressed up as their favorite Star Wars character.
Three "Fun Ponchos" were made by Ben Cooper: Yoda, C-3PO, and Darth Vader. The last one is unique in that Vader is spelled "Vadar" on the package front.
