No, it's not by Stovel. Published by the City of Winnipeg. Photos were by Steele & Co. Printers were Telegram Printing -- same printers as for the large hardcover Martel book that was printed about the same time (and reprinted a few years ago) and apparently for "Winnipeg Queen of the Prairie" (1902), another viewbook I picked up 5 or 6 years back. Steele & Co. seems to have been the leading producer of photographic imagery of this type in Winnipeg at the turn of the century.
I don't think I have any by Stovel, although the booklets don't always list any publisher or printer information. It would be interesting to find out how many of these viewbooks were printed. I have about 10, I guess.
