I have been searching around on flea markets and yard sales for lovely vintage books. And I have found some! A lovely old atlas, with beautiful yellowed maps. And an old music book with marvelous vintage looking (yellow/brown) pages. A book on how to make (crossword and other) puzzles (?). The pages have illustrations of puzzles and text combined, making it great collage pieces.
The link to my Etsy shop is on the right hand side on this page. Check it out and get some pages before they are gone!
