Toronto Litho early coloured litho series

A third card (for me) in this early colour litho series by Toronto Lithographing Co. Unlike the others, this is identified with W. R. Adams, Souvenir View Cards, Toronto. Assuming that these were produced in Canada, they may be one of the earliest colour lithograph series of postcards to originate in this country. I would think that Toronto Lithographing Co. would have done its own printing work on all of its cards.
