Mauro: Don't know why that would be. Here's what I get
% ipython --pylab
In [3] from mpl_toolkits.basemap import Basemap
In [4]: m = Basemap()
In [5]: c = m.drawcountries() # map pops up with country boundaries drawn
In [6]: type(c)
Out[6]: <class 'matplotlib.collections.LineCollection'>
In [7]: help(c.remove)
Help on method remove in module matplotlib.artist:
remove(self) method of matplotlib.collections.LineCollection instance
Remove the artist from the figure if possible. The effect
will not be visible until the figure is redrawn, e.g., with
:meth:`matplotlib.axes.Axes.draw_idle`. Call
:meth:`matplotlib.axes.Axes.relim` to update the axes limits
if desired.
In [8]: c.remove()
In [9]: draw() # countries disappear from map.
