Lot of 77 Vintage/Antique Canada Canadian Postcards

This is a varied lot of postcards from Canada.  A few are posted so I can see dates from 20s-60s and possibly one earlier (hard to read the dates).  Most are not marked so I do not know the years.  They span across Canada but most on East Coast. There are some in sleeves and a couple are duplicates. The fold out looks like it was from one of those fold out booklets but no booklet is here. Please see photos for condition and let me know if you have any questions as I am not a postcard collector so I am not sure what to highlight here.
