Recent Sales

Comics from this publisher (Harrier) generally sell for low amounts ($2-$10) at auction unless they are key issues like 'Swiftsure' or 'Avalon'.

Grading Recommendation

Not recommended for professional grading. The costs of grading, shipping, and handling would significantly exceed the market value of the comic in this mid-to-high grade condition.

Notable Features

First Harrier edition of this newspaper-style format. Notable for being part of the mid-80s British 'independent explosion' led by Harrier Comics and its founder Martin Lock.

Authentication Notes

The item appears authentic. The print quality matches the 1986 UK independent standard. No indications of reproduction or counterfeit exist for these low-demand indie titles.
