This Riddell SpeedFlex beautiful alternate helmet has been hand signed by both J.J. McCarthy and Justin Jefferson, making it an elite dual-signed collectible for any Minnesota Vikings fan.

The helmet features the Vikings’ sleek white alternate design with purple horn graphics and a chrome-style facemask, giving it a modern on-field look. Both autographs are cleanly signed in bold purple marker on the shell and display beautifully against the white finish.

This is a premium SpeedFlex model — not a basic replica — making it a high-end display piece built for serious collectors. A dual-signed helmet featuring Minnesota’s star wide receiver Justin Jefferson alongside quarterback J.J. McCarthy represents both the present and future of the franchise, adding strong long-term collectible appeal.

The helmet includes Beckett Authentication Services (BAS) certification with matching hologram verification as shown in the listing photos.

A true centerpiece item for any Vikings collector looking for a bold, modern, dual-signed display helmet.
