This listing features a nice Michelin map of Switzerland, 1998, map #927.  it measures 4-1/2" x 10" in its normal folded state and approximately 45" x 20" when opened and expanded.

It is in excellent condition.  See the "Condition description" and photos for more details.  The photos implied some inconsistent coloring, but it is a lighting issue--the color of the map is bright and consistent--no fading.
