my name is Roberto Cavaliere, excuse me for my incorrect English
I have a problem with SetOptions; I want to set the option Axes
for the function Show, but it has not any options in the Options
If I write :

> In[1]:= SetOptions[Show,Axes->True]
> Out[1]:= Axes is not a valid option for Show  

but if I write 

>In[2]:=  Show[graphic1,graphic2,Axes->True]
>Out[2]:= -Graphic- (a graphic with axes )

all things go right.

If I write :

>In[1]:=  Attributes[Show] = {};
          Options[Show] = {Axes->False}
>Out[1]:= {Axes->False}

>In[2]:=  Show[graphic1,graphic2]
>Out[2]:= -Graphic- (a graphic with axes )

Why SetOptions don't work ?

Why Mathematica do this, and can I set the option Axes in a 
definitive way ?

Thanks in advanced.
