I believe your card is from a set as listed. All have the same back, same sort of printing and layout, also most have Souvenir from Ulverstone Tasmania or Souvenir from Devonport Tasmania printed on the front of the card.
The Ulverstone cards were published by W.A. Skinner Newsagent Ulverstone and the Devonport cards were published by W.W. Pettit Bookseller Devonport.
Probably published sometime in late 1904. Not sure how many were in each set, perhaps 6 ? I can list the following,
All the following 9 cards have this back.
Ulverstone
1. Furners Hotel / Scene on the Leven River. (I don't think this was intended as a advertising card, just that Furners Hotel was and still is a prominent building in Ulverstone.) There is no Souvenir from Ulverstone printed on this card. My copy is postally used 1/11/09
