Argument #1
Ms. Gilleo should be allowed to hang the sign in her window. The city ordinance prohibiting such displays is unconstitutional since it places content restrictions on certain kinds of speech.

Argument #2
The Court should allow the city law to stand. The law was enacted for a valid and neutral reason--in order to prevent property values from going down due to visual clutter resulting from signs.

You can now proceed to the Supreme Court's decision in this case.
