Advice needed for adhering acrylic pieces on wall

permanent signage is typically done with the 3M tape or sometimes (depending on how the sign is built) with tiny brads. i know the acrylic logos we attached (before we had a laser cutter and had a signage vendor do it) was done with the nails.

i used brads from home depot with this two-layer acrylic technique to do my house numbers.

much less destructive, just two tiny holes to spackle in if you take it down.
