Allen (Canada) sent a wonderful contribution for the Houses in the Mail project, containing several different types of housings. The bright envelope (made of a calendar), shows another tipi, that one belongs to an UNESCO WHS called Head-Smashed-In Buffalo Jump.
This loghouse shows the traditional housing style of Haida people. The totem pole means who live in the people, and also depicts religious beliefs.
And still more houses!
This is an Italian house, but the sender wrote that it reminds him a lot the landscape where he lives, near the Rocky Mountains, surrounded by prairies.
And a mini-postcard with a lovely winter scene...
