Spike Lee had the legendary West 4th Street courts lookin' like a Knicks block party on Monday ... just hours before tip-off of the most anticipated basketball game in NYC in decades!

The Academy Award winner and NYK superfan pulled up to The Cage in a royal blue and orange wrapped bus, the Fanatics Fan Wagon, around noon -- as scores of fans surrounded the bus to chop it up with Spike, before he heads to the Garden for tonight's game.

Lee and Fanatics hooked fans up with autographed memorabilia, including a signed Karl-Anthony Towns jersey.

Thanks to the bus, fans were also able to purchase last-minute Knicks apparel.

If you missed Spike today, don't sweat it too much ... we hear some other legends may be popping up over the next couple of days.

As for the series, the Knicks lead the NBA Finals 2-0 after going into San Antonio and shocking the favored Spurs.
