Lift your bottom lip so its inner edge (where the wet part meets the dry part) touches the very bottom of your top front teeth. Add vocal cord vibration as you blow air through.

Americans pronounce vintage as VIHN-tuhj (/ˈvɪntɪdʒ/). In "vintage", the "t" right after N is dropped — the tongue skips the T stop and moves directly from the N position to the next sound. This is called the Silent T after N, the kind of sound shift that makes everyday speech feel effortless. It comes out as VIHN·tuhj. Stress falls on the first syllable — keep everything else short and quick. You'll hear it in sentences like "He collects vintage stamps from all over the world" or "The photograph was taken using a vintage film camera" — more examples below.
