One idea could be to get him a vinyl record of one of Led Zeppelin's albums, like "Led Zeppelin IV" or "Physical Graffiti". Alternatively, you could get him a book about the band, such as "When Giants Walked the Earth: A Biography of Led Zeppelin" by Mick Wall. Another idea is to get him a piece of band merchandise, such as a t-shirt or a poster featuring the band's iconic symbols or album artwork. If he's a fan of craft beer, you could also try finding a local brewery that has a Led Zeppelin-themed brew and create a gift basket filled with the beer and some Led Zeppelin memorabilia.
Or you can get him a star map with the date of your anniversary.
