Not postally used but with the message: "Don't know whether you have had these cards before. Am busy this week but hope to write long letter next week. Hope you are all well. I am A1 - OK Fine. [last line in very large lettering] This is by Rumsey & Co, in their Canadian West Series, No. 2 (30 subjects).

Warwick Bros. & Rutter card 3102 -- a slightly different design than the other three Frank slide cards. This one shows where the miners were entombed. It is on the fancy Warwick divided back (the others have the boxy "Canadian Souvenir Post Card" back, undivided in one case and divided in the other two).
