Abstract: A multi-leaf page for mounting substrate articles comprises an imperforate base leaf, a top leaf, and an intermediate leaf positioned between the top leaf and the base leaf. The base leaf, the intermediate leaf, and the top leaf are arranged in overlying parallel relation and are joined together at edges thereof such that the leaves can be pivotally separated from one another to enable the substrate articles to be mounted therebetween. The top leaf and the intermediate leaf include a pair of aligned windows for enabling a substrate article to be mounted to the base leaf and exposed through the aligned windows. The top leaf, the intermediate leaf, and the base leaf have imperforate regions overlying one another where no windows are formed in any of the leafs.
