HSC-21 Blackjacks Holographic Decal - Design Overview

This die-cut holographic vinyl decal vividly captures the spirit of Helicopter Sea Combat Squadron 21, the U.S. Navy's "Blackjacks." The design centers around the squadron's namesake, the "Blackjack" playing card, a potent symbol of their identity and mission.

Visual Elements & Representation

At the heart of the design, the iconic playing card motif is reimagined with a modern, military aesthetic. The card features prominently, potentially showcasing a stylized Ace of Spades or the "Blackjack" hand itself. The holographic finish adds a dynamic element, creating shifting colors and a shimmering effect that mirrors the versatile capabilities of the squadron's MH-60S Seahawk helicopters, operating across various environments.

The design may incorporate elements referencing the squadron's diverse mission set. This could include subtle visual cues, such as stylized silhouettes of the MH-60S, or representations of the mission symbols such as a life ring for CSAR, a ship's silhouette for anti-surface warfare. Elements could be incorporated to represent the mission set, such as a life ring for search and rescue operations or a silhouette of a ship to represent anti-surface warfare.

Symbolism & Meaning

The "Blackjack" card acts as a focal point, symbolizing both the squadron's nickname and the calculated, strategic nature of their operations. The presence of Navy imagery may serve as a reminder of the squadron's connection to the larger naval mission. The use of a holographic finish reflects the squadron's dynamic presence in the air and the ever-changing environments they operate in. Overall, the design encapsulates the essence of the "Blackjacks": their skill, adaptability, and dedication to their mission.

Holographic vinyl decals with a high-contrast rainbow sheen, printed with eco-friendly inks on premium, weather-rated film. Waterproof, UV-protected, and available in five sizes.

Built to turn heads and hold up outdoors. These holographic decals use premium printable vinyl topped with a UV-protective laminate. The film is rated for multi-year outdoor exposure, so the color stays bold and the surface resists scuffs and sun fade.

  • Signature finish: a 99% opaque rainbow effect that shifts with angle and light—clean edges and a smooth, matte-sheen feel rather than a mirror gloss.
  • Waterproof: designed for rain, splashes, and regular washing on smooth, non-porous surfaces.
  • Eco-conscious printing: vibrant, high-density color produced with eco-solvent inks for sharp lines and rich gradients.
  • Color guidance: no white underbase is applied; pure white areas won’t print, and very light tones allow the holographic layer to show through. Darker tones deliver the strongest contrast.
  • Easy-peel backing: release liner separates cleanly for quick, bubble-free placement.

Made for smooth surfaces: glass, metal, coated plastics, sealed laptops, bottles, mirrors, lockers, and windows. Suitable for interiors and short-term exterior spots like vehicle windows or signage.

  1. Prep: clean the area with mild soap and water or 70% isopropyl alcohol; let it dry fully.
  2. Apply: peel, align, and press from the center outward with a card or squeegee to push out air.
  3. Set: allow 24 hours for the adhesive to reach full bond; avoid heavy moisture during this time.

Tips: Avoid heavily textured or silicone-coated surfaces. For curved items, apply slowly and don’t stretch the film.

  • Wipe with a soft, dry or slightly damp cloth from the center outward to lift dust and grime.
  • Avoid abrasive pads, harsh solvents, or pressure washers that can dull the holographic layer.
  • If placed on bottles or mugs, hand-wash is recommended. Prolonged high-heat cycles can shorten adhesive life.

Available in five sizes. Measurements refer to the longest side of the decal. A “3 inch” option is 3 inches across its largest dimension; the die-cut follows the exact contour for crisp, professional edges.
