There are several such resources on this website with the English text, I'm not sure if there is a ready made Latin card. I made my own as well by copying from the Parish Book of Chant (available as a free download). I can send you a copy, but we only did the Sanctus and Agnus Dei in Latin, memorial acclamation was in English and we never have sung the creed (I was literally laughed at for even suggesting that we try singing it to commemorate the year of faith).

ICEL has the Sanctus and Agnus Dei in Latin in modern notation. I think the Gloria is only in English though.

This reminded me of what one of our schola directors made for the congregation. He used card stock and printed four different cards for the liturgical year with a different Gregorian chant mass setting and the appropriate Marian antiphon on each.

Sundays after Pentecost (green): Mass XI (Orbis Factor) and Salve Regina
Advent and Lent (violet): Mass XVII (In Dominicis Adventus et Quad.) and Ave Regina Caelorum and Alma Redemptoris Mater
Christmas (white): Mass VIII (De Angelis) and Alma Redemptoris Mater
Easter (yellow): Mass I (Lux et Origo) and Regina Caeli

Unfortunately, that director moved out of state and I'm actually at a different parish now as well. They were very popular, though. I can make a sample pdf and attach it if you'd like. If I remember correctly, they were about half the size of an 8.5 x 11 page.

It is to me a matter of dismay that, despite the constitution on the liturgy, many or most parishes (UK) sing hymns instead of singing the Mass and, where the Mass is sung this is limited to the ordinary, mostly in English, and propers are omitted. Where Latin ordinary is sung, the congregation usually have nothing to follow, and this can generate criticism of singing the Mass in Latin.

Like those in this discussion, I have yet to find a source of laminated pews cards for Latin Masses. Generally, publishers are not interested - they can sell hymn books at a decent margin - production of pew cards for each Mass would be disproportionately costly and the margins too slim. CMAA's Book of Parish Chant and which I imported for our schola, is wonderful but, it is unaffordable as a pew book and, you only need look at the condition of pew hymn books to conclude that these - and even a limited Latin booklet as we had in my previous parish, would become dog-eared wrecks unworthy of handing out.

My suggestion is that CMAA step up to the task and produce a selection of pew cards online, one card for each Mass and to include the Gloria. It would not be practicable to include the Credo - that would need a separate series of cards, for ideally Credo I and Credo III - although, some parishes might be more adventurous than this. The cards would be available worldwide for printing, perhaps at a fee to offset CMAA's expenses, and parishes could make their own arrangements for lamination - laminating devices are not expensive.

I produced pew cards for my previous parish, but used modern stemless transcriptions. Depending on the length of the ordinary, they can be quite cramped, but it can be done. Our cards for Advent/Lent even have ibterlinear translations. I can share them here if that would be helpful.

I think these are still available in the UK -

It might be worthwhile to do some experimenting to figure out what formats would be attractive and useful: 8.5 x 11, folded in half, or in thirds; maybe 8.5 x 14 ("legal size")? 11 x 17 trifold? Is card stock easily available in all these sizes?

Any of these can be printed at copy shops and office-supply stores, but some people don't have a budget that allows for any outside printing. So the biggest formats with the most room to make attractive results are not going to work for everybody.

Here's a first attempt to provide what @bcb was asking for (two versions, depending on which paper size one uses).
