An original design by Willette, in which he drew a little girl kneeling before
one of Mucha's masterpieces (see PL.182), assuming it
to be a picture of a saint. Thus we have "The Pious Error" an amusing
little composition that displays Willette's exceptional drawing skill.
Subscribers to the Maitre de l'Affiche
series received four special plates annually. These premium original
lithographs, each an original design, were created specifically for
this series, and are not seen in any other format, unlike the regular
plates, which are reduced versions of larger posters.
We are most fortunate to have had the inclusion of the Special
Plates (Sp), as each one is a true example of the artist's creativity
and skill. The artist is unencumbered with a product or service
to advertise, and can express himself more freely, demonstrating
his drawing ability, the essence of graphic art, with only one or
two colours. For many collectors these unique Special Plates are
more desirable than any of the regular plates.
