These postcards are not as cool as Pam G's Stuff but I really like these 2 old postcard I've picked up in the last few months. The color one is Postmarked Jul 6, 1935 and the black and white picture is postmarked July 14, 1942
You will notice that the smoke shop and the cafe on the right remain in 7 the years while Club Reno becomes Harrah's Bingo (from what I can tell).
They also updated the Reno sign in the 7 years between the 2 pictures.
Enjoy
