I fell absolutely in love with the font that they used at the Montreal Museum of Fine Arts exhibition of Yves St Laurent’s works.

It’s essentially this font but imagine it without the lines to connect the letters.
Looks like Helvetica Ultra Light to me.
Oh sometimes we make other missteps. I was using District Thin but am thinking it wasn’t the best.
