I've never been to Milwaukee, but I understand you mean this sign;

however, I'm willing to believe back then BP would have checked
around the streets surrounding Lake Park and referred to maps &
asked about and visited notable landmarks. (Mitchell Hall is on a
corner with a numerous bus stops surrounding it.)
Interestingly, here is the only actual example of a '
harpsichord'
that I've found in Milwaukee - in the Art Gallery on one of those
three stories of Mitchell Hall...
If you ask to view the mezzotint of the "
woman, with harpsichord
silently playing" (...at hanky panky), they may refer you to this;

That mezzotint picture from 1794 has an Object ID beginning with
the notation '2001', which tends to suggest that that may be the
year the Art Gallery received it - but maybe that was the year it
was recorded as belonging to the gallery, it occurs to me that
possibly some Milwaukee grandee loaned it to the gallery in or
prior to the early 80's (the picture subject matter conceivably not
being particularly appropriate to some 20th Century personal tastes)
and perhaps the owner eventually decided years later that the
gallery could keep it permanently.
Shrug. I guess it would be necessary to do further research with
the gallery to determine if in fact the gallery could have had that
picture on display on its' walls back in the early 1980's, for BP to
have seen it.

Isn't Shorewood north of UWM?

I was unable to get your links to work, i am not well versed in attaching them myself. I do have images collected from the 1980 atlas with the Metro Milw. area on one half, the points of interest on the other, with Mitchell park domes being top center. Also, in going through my 1982 World Book Encyclopedia, the Mitchell Park domes are also listed when researching Milwaukee. They were one of the BIG points of interest in the day, and they tell three "stories/ecosystems" that of the Desert, Tropics, and the Floral Show dome with represents the other 4 bio/ecosystems of forest, deciduous, grassland, and tundra. (BTW our corpse flower should be in bloom for another day or two
) I have a strong feeling the general consensus on the Pabst Theater being the Woman with Harpsichord silently playing, is correct in that yes, the female bust is playing a lyre (a type of harp) on the building, in the building the Harpsichord was an instrument strongly tied to the Baroque period performances played in the German theater. Which would tie into Wagner's Ring and the Rhine maidens. (I have played with the idea that maybe Byron was playing with the word also, Harp C chord - how a harp, lyre, lap harp, harpsichord is played, plucking strings vs a piano where strings are struck). The Pabst Theater has architectural features that are also portrayed in the image, mainly in the cowl of the dress/cloak you can see these around the doors and the arch above the doors. I have yet to find an actual photo of the Mitchell Park Domes advertisement that had been on the East facing wall of the Pabst, but I have been able to get pictures of other advertisements on that wall. Also, another quirk, you can spell out Capt. Pabst from the first letters of the verses.
I will have to double check on the Milwaukee/Shorewood/ dividing line of the 80's, you may be correct, i may have misspoke, but as a long time resident... lake park and UWM are a not "the city". lol
