I like to peruse the books at thrift stores & I often end up buying a few. When I was in Alberta a few weeks ago I picked up a few.
Sometimes I have discovered some odd bookmarks that people have left in the books, but this last one was by far, the most useful to ME.
Occasionally it's a shopping list, sometimes a photo, but when I took this bookmark out, there was much rejoicing.
Nine Canadian "always" stamps. Not only did it cover the cost of the book, but I might be able to afford a few more now!
