About Series : Wide Series
This series have full width images, but have an identical back to the Vignette series. Both series can be identified as John Walker productions by the logo, an anchor in red separating the words POST and CARD.
This series has an undivided back, which was the post office requirement in Tasmania until 1905. Only one card has a usage date, of Feb 14, 1907.
The photographer is not identified on the cards, but at least some are by Sirius, which is a pseudonym of Charles Gruncell. Gruncell was a schoolmaster and photographer in Hobart.
Cards of this series were clearly manufactured by John Walker & Co, but bear the name of W.R. Propsting on the back, presumably a paying customer.
