An artistic mystery: could this car be a Métallurgique?

I would be grateful for readers opinions.
 

George Wright and his brother Gilbert Scott Wright are famous for their horse portraits and hunting scenes. Miniatures of their work was also used on box tops and glasses. It would seem that George Wright did a contemporary series of car images, normally in association with horses for some publication which I have not been able to determine. I have a record of 15 such automobile portraits. The interesting feature is that the horse people and motorists are in harmony and this image is the first I have seen of the horse being disturbed. We know in the past that there was a lot of antagonism between riders and automobilists. For further examples of George Wright's automobile work see my website Motoring Art Information. It can be seen that he accurately depicts early cars showing a specific model, hence I am confident that this is a manufactured automobile.

I would welcome identification of the automobile and also the publication where this series appeared.
