An alternative is peel-and-stick repositionable textile fabric. Very versatile because can stick on anything: walls, doors, cabinets, ceiling, glass, metal, bathtub lol...
Removable and won't damage wall paint. Easily cut to make your own weird wall decal shapes if you want.
The complete lack of glare makes up for the matte surface, so it often appears clearer on the wall than satin prints behind glass.
I use PhotoTex which is (last I checked) sold under several brands, including Canon, LexJet, Kodak. Not sure about HP's label. I've been using the Canon label for no particular reason other than easy availability for me.
FWIW, I compared it with Breathing Color's Art Peel and the PhotoTex had much smoother surface (finer texture), was brighter/whiter (out of the box; of course none of these are colour stable for long periods), higher opacity (important on glass), and better colour gamut and black point. The BC also separated from its backing in the printer and jammed.
I think I've posted here previously with more detail, check the search if want to know more.
