Use the maker’s resource and a clearly attributed application
Youssef Habchi’s Streamster page identifies the script resource and its commercial acquisition options. In the October 2017 Some Retro Arts project, Johnny Feron explicitly credits Streamster by Habchi for the New Sensation poster. This is a dated designer credit for one application, not a claim that all retro posters use Streamster or that the font was created in the 1980s.
Compare the script silhouette before a neon-style effect
For an original music-night graphic, set one short phrase in a single colour with no outline or glow. Inspect the word shape, joins and the space at the beginning and end of the line. Duplicate it and add a restrained glow as a separate effect; compare whether the glow closes gaps or makes adjacent letters merge. Keep the unmodified version so you can distinguish a lettering problem from an effect problem.
Keep the date and artist details out of the display effect
Place the time, venue and supporting performer name in a quieter reading face and inspect the final small preview. A title that looks balanced on a large square may need a different line break on a narrow event card. Yellowtail and Mr Dafoe are independent script comparisons, not Streamster editions. The homepage flowing text styles for messages replaces Unicode characters rather than installing Habchi’s family or exporting the glow and layered poster composition.
Your questions, answered.
Does the 2017 poster credit date the original font’s creation?
No. It documents use in that project, not the font’s first drawing or release date.
Is a neon glow part of ordinary copied text?
A layered visual effect is separate from the font and the character string. Copying styled Unicode text does not carry that artwork.
