over spray removal

[oldguy]

Hi guys & gals, I have this sign I got off of the outside of a building I used to work at when they removed the payphone. it was in the late 80s or early 90s. at some point in time they paint the building & got over spray on it. I don't know what kind of paint they used. does anybody have any good ideas on how to remove the over spray, without harming the original sign paint? The top picture is the good side.

Thanks for any help

Since it's probably latex paint, I would try alcohol, such as isopropyl or denatured.  It will soften the paint but will take a bit of scrubbing.  It should be pretty safe on the original finish, but the usual warning applies about testing in an inconspicuous corner.  Goof-off will cut through the overspray fast, but is pretty risky for damaging the original finish.
