Vintage 1970s Six Flags Great Adventure Orca Water-Ski Show Photo Lot of 11

Lot of 11 vintage color snapshots, each 3.5x5 inches, documenting a 1970s Bicentennial-era theme park visit, likely Six Flags Great Adventure in New Jersey (unconfirmed). The set includes a water-ski stunt show at a stage marked 'SONAR LAB' amid pine forest, and a separate lagoon show featuring a colonial 'REVOLUTIONARY SUPPLY COMPANY' building backdrop with a costumed Revolutionary War-era flag bearer and multiple dynamic shots of a killer whale (orca) leaping before spectators. All prints show the heavy pink/magenta color shift typical of aged 1970s Kodak film stock; a few frames include spectators' heads or silhouettes in the foreground for candid depth. No handwritten captions are present on these scans. Photos are unattributed to named individuals but form a coherent themed sequence of the same park visit, likely mid-1970s given the patriotic Bicentennial decor. Condition: consistent color fading/magenta cast across the lot, otherwise stable with no major tears; some images slightly soft focus. Associated with the estate of USAF Col. Patricia Jane Harrington. Please review photos for condition.
