Vintage 1970s Mattel Ken Fashion Collectibles No. 1376

This is a vintage, new-old-stock Mattel Ken Fashion Collectibles outfit, specifically number 1376, manufactured around 1978-1979 as indicated by the copyright date on the internal card. The ensemble features a short-sleeved, white knit textured shirt with blue trim on the collar and sleeves, accented by two blue faux pockets. Accompanying the shirt are long, light blue denim-style trousers featuring white top-stitching details. The items remain sealed in their original clear plastic blister pack attached to a yellow cardboard backing. Notable features include the original Mattel logo in the upper right and a pink illustrative card in the bottom left showing the outfit on a Ken doll. The condition of the packaging shows significant wear typical of its age; the cardboard backing is heavily creased at the top with paper loss and several original price stickers from retailers like KB Toys. There is visible yellowing of the blister plastic and general edge wear. The interior clothing appears to be in mint, unused condition, preserved by the seal, reflecting the late disco-era fashion style of the period.

I have conducted a visual examination of the Vintage Mattel Ken Fashion Collectibles No. 1376, dated circa 1978. This item is a quintessential example of the 'Superstar' era Ken aesthetic. The outfit—a textured knit shirt and contrast-stitch denim trousers—remains factory-sealed under the original blister pack. Based on the Mattel branding, specific typography, and the 'K•B' (Kay-Bee Toys) price sticker, the item appears authentic to the late 1970s production period. Condition is the primary driver of value here. While the clothing is in mint, 'New Old Stock' (NOS) condition with crisp whites and vibrant blues, the packaging is in 'Good' rather than 'Fine' condition. I observed significant creasing across the top hanger tab, paper loss, and corner softing. The plastic blister shows characteristic 'ambering' or yellowing common in 1970s polymers. Market demand for sealed Ken fashions is steady but lower than for Barbie fashions or early 1960s 'mod' Ken items. Similar 1300-series outfits in comparable retail-worn packaging typically realize $40–$70 at specialty auctions. The presence of multiple vintage price tags adds a layer of nostalgic provenance but does detract from the visual purity of the card. Full authentication is limited by the digital nature of this inspection. A physical examination is required to verify the integrity of the factory seal (ensuring no re-gluing) and to check for hidden storage damage such as dry rot or 'sticky leg' syndrome beneath the fabric. Scientific testing of the plastic stabilizers and fiber analysis could definitively confirm age, but is generally cost-prohibitive for items in this price bracket.
