Help Needed

A long time ago, I was reading an article at a sedevacantist website about the liturgical reforms that culminated in the Novus Ordo in 1970. The article looked back to the reforms of the early twentieth century.

What made this article memorable was that it had this graphic, a larger rectangle divided up into smaller rectangles. They each contained a specific year when a reform was promulgated (for instance '1945' for when the Psalter of Pius XII came out). The years went from left to right from earlier to later. The first box was white and as one went left, each box was greyer than the one before it, representing the supposed diminishing of the liturgy.

I'm doing some reading on the subject and if anyone knows of this website and can direct me to it, I'd appreciate it. Thank you.
