This was no da Vinci.

A sketch of Manhattan’s skyline by President Trump sold for $6,875 at auction Thursday night.

Then again, it hasn’t been retouched like Leonardo’s “Salvator Mundi,” which someone bought for a record $450.3 million a day earlier.

Nate D. Sanders Auctions said the president drew his Big Apple mini-masterpiece for a 2009 charity event benefiting the East Texas Literacy Council.

He signed both the sketch and a photo bearing his squinty portrait — with the inscription “Think Big!” — with the same gold marker at the charity event.

In October, Trump’s black marker sketch of the Empire State Building fetched considerably more — $16,000, about $4,000 above the estimated sale price – in a sale by Julien’s Auctions.

Real-estate mogul Elie Hirschfeld, a former Trump business associate, was its buyer.
