This is a series of b&w cards, probably printed by J. Walch & Sons themselves at their printery in Hobart.  There were two printings of the series; one with brown back and the other with black back. It is not clear which printing was first.

Series Contents: The full list of cards in the series is not know; the ones I have seen are illustrated here.

Date Published: Published in 1906. The earliest postmark date I have seen is 22 Dec 1906.   This series seems to have been published after Series E, of which the earliest date seen is Oct 16, 1905.

Printing: The cards were printed by letterpress halftone. J. Walch & Sons had had this type of printing press in their own print shop in Hobart since 1900, so it is most likely that the cards  were printed there.

Number in Series: Unknown.

Identification:  As well as the different coloured ink for the back of the card, there is a difference in the layout of the imprint along the left margin.

Brown back:
