It is advertising man I took a marketing class lol I know advertising when I see it even if I got a D+ in the class. It says "we've got all your longboarding needs." Who is "we"? They're the people selling boards lol.
And picture number two is also an ad, for some board company (idk which one) but it know for a fact that EVERY longboard isn't built with precision so this board company obviously prides themselves on that quality so they made an ad about it (:
