Mark Hamill is authenticating signed Star Wars merchandise for fans on Twitter

"Hope everyone can learn my real signature to help prevent fraudulent dealers!", .

As we all know, "Star Wars: The Force Awakens" takes place a long time ago, in a galaxy far, far away - but its most breathtaking setting isn't almost so inaccessible.

Hamill has a notably warm-hearted attitude toward Star Wars fans.

Disney Parks / YouTubeMark Hamill has taken to Twitter in an effort to save "Star Wars" fans from spending money on items with fake autographs. "For dinner at dad's house", Hamill wrote on a picture of Carrie Fisher, Harrison Ford and other Star Wars actors standing at the head of a dinner table tweeted by a fan.

Be sure to to see multiple examples of what his real signature looks like so you too won't be fooled into buying an imposter.

Of note, he verified several autographs on vintage Star Wars cards that included some snarky notes that have gone viral online in recent months. The internet is already rife with proof of the real-life Luke Skywalker's expertise on the matter, but when fans began tweeting images of items available for purchase supposedly signed by Hamill, he responded to each request. "Never thought they'd go public".
