5975. Winter Scene, Bow River, Calgary.

Pearson's PEERLESS POST CARD, posted at Calgary on Jan. 28, 1910 to Miss Alberta Flewelling, Box 135, Dundas, Ont.

"Calgary, Jan. 28th Dear Bertie:- We are having excellent skating weather now. The evenings are glorious - mild and moonlight. Have you seen Halley's Comet? It is visible here for about an hour each evening. With love, yours - Madge."

I've never seen a reference to Halley's Comet before.

The card also says "Published by Pearson, Stationer, Calgary".
