Wow... To be printed in 1963, this must have been planned for quite some time... Thank you for sharing!
After the 1962 missal was released, there were a series of "new" missals from 1963, to 1965, etc leading all the way up the new mass in 1969. The period of 1963-1968 was full of constant change. Some diocese were more "experimental" than others. There are many black-n-white pictures, from this period which show the laity walking up the aisle of the Church to "give the offering".
The changes in the Church liturgy started in 1963, not in 1969 with the new mass.
