How about a personalized vinyl record of Louis Armstrong's greatest hits? You could also include a turntable if they don't have one already. Another idea could be a framed print of a Louis Armstrong concert poster or a photograph of him performing, paired with a handwritten note wishing them a lifetime of happiness together. A Louis Armstrong biography or a jazz-themed cookbook could also be great gifts for music-loving newlyweds.
Or you can get her/him a star map with the date of the wedding.
