Harley Quinn #51 Guillem March Summer of Superman Variant Cover (DC Comics, 2025) – A Vibrant Collectible with Rising Investment Potential
Add a splash of chaotic charm to your collection with the Harley Quinn #51 Guillem March Summer of Superman Variant Cover (DC Comics, 2025). This limited-edition variant, featuring Guillem March’s stunning artwork, is a must-have for Harley Quinn fans and savvy investors looking to capitalize on DC’s hottest titles and the Superman craze.
Key Appearances: Set for release on May 28, 2025, Harley Quinn #51, written by Elliott Kalan with art by Mirka Andolfo, dives into Harley’s wild world as she navigates a murder accusation in Gotham City. The issue pits Harley against Batman, who hunts her down on Coney Island, leading to a clash that questions her innocence. The Guillem March “Summer of Superman” variant cover steals the spotlight, showcasing Harley in a Superman-inspired costume with her signature diamond-shaped “S” shield, tying into DC’s Superman-centric event. This issue also teases the “Trials of Harley Quinn,” adding narrative depth to her evolving anti-hero arc.
Current Value: The Guillem March Summer of Superman Variant is a collector’s gem due to its limited print run and March’s acclaimed art, known from Gotham City Sirens. Retail-priced at $4.99–$5.99 (card stock), raw near-mint copies are fetching $10–$30 on eBay, with CGC 9.8 graded copies projected to hit $50–$150, especially for 1:25 incentive variants. Harley’s prominence as DC’s “fourth pillar” alongside Batman and Superman drives demand, with her variants consistently selling at premiums.
Expected Value and Trends: Harley Quinn’s popularity is soaring, fueled by her role in Joker: Folie à Deux (2024) and DC’s Summer of Superman event, spotlighting Superman-related content like Superman: Legacy and a new Supergirl series. Harley’s Superman-inspired look ties directly into this hype, mirroring the market boost seen with themed variants like DC’s Swimsuit covers. Previous Harley variants, such as Harley Quinn #40 (2024), have appreciated 50–100% in high grades within a year, and this cover could reach $75–$200 in CGC 9.8 by 2026, especially with Harley Quinn Month (February) and Alien Day (April 26) boosting collector interest.
This Harley Quinn #51 Guillem March Variant blends vibrant art, a pivotal story, and strong investment upside. Perfect for fans of Harley’s chaotic energy or collectors betting on DC’s Superman surge, this comic is a standout. Don’t miss out—grab this rare variant before prices skyrocket!
