For a project like this you might want to consider that just the list of all those Gemeinden fills a book with more than 300 pages:
Friedrich Zahn: "Gemeinde-Verzeichnis für das Königreich Bayern nach der Volkszählung vom 1. Dezember 1910 und dem Gebietsstand vom 1. Juni 1911", Lindauer: München, 1911. 380 pages
Bavaria is quite big and now has 2056 Gemeinden. For the time frame in question that number goes up to over 7123 (Wikipedia starting point for the year 1952, prior to 1930 those number is still higher) entities whose boundaries would have to be painted into a map.

Image shows: Poster "Population, area and number of municipalities in the administrative districts of Bavaria 1971" (before the start of the territorial reform) (Archive for Christian Social Policy)
That means that just the district Cham has how much Gemeinden?
-> 38 subdivisions. 39 today:
The present day subdivision into Gemeinden is on this Wikipedia page:
Liste der Städte und Gemeinden in Bayern.
See the sometimes very complicated boundaries and the high level of detail required in a zoomable vector format; that is how deep you have to zoom in to make out anything precise. And this is present day – after a lot of simplification and territorial reform. I included the pixel format here in the biggest resolution Wikipedia allows (revealed on click). The result is pretty uselsss in my eyes. Earlier maps must include not only a lot of adddtional boundaries corresponding to the more than 7000 Gemeinden. Those older maps also would have to account for the sometimes irrationally medieval looking wobbly boundaries and a number of exclaves/enclaves, and quite a number of unincorprated territories: territory that is not part of any Gemeinde but still would have had boundaries to them. The needed detail just for boundary lines increases therefore quite significantly. If you then want include just the names or any other feature you need a lot of ink. Those territorial reforms were not entirely futile after all.
"That is a bit much for printed material on one map", thought Mr Luber in 1880 and split that up into government district level. That was then published in 8 maps:
L Luber: "Übersichts-Karte der Gemeinden, Amtsgerichte und Bezirke des Königreichs Bayern: nach dem Stande des Jahres 1880"
Titel: Übersichts-Karte der Gemeinden, Amtsgerichte und Bezirke des Königreichs Bayern
...: nach dem Stande des Jahres 1880
Maßstab : Ca. 1:300 000
Verf./Bet.Person: Luber, L.
...: Statistisches Bureau
Angaben zum Verlag: [München]
OCLC-Nr.: 643501908 (Bayerische Staatsbibliothek bsb-muenchen.de)
Those are split along the administrative Regierungsbezirke level: Oberbayern, Niederbayern, Oberpfalz und Regensburg, Oberfranken, Unterfanken und Aschaffenburg, Schwaben und Neuburg, Mittelfranken, Pfalz.
These maps are available, but only offline. You might of course digitize them yourself, then stitch them together. If that is intended to be printed somewhere in an article or book that seems not very feasible.
To get much more detail then that –– and too big a choice already, from a still incomplete project started in 1906 –– you might need to have to turn to the official Historical Atlas of Bavaria:
Historischer Atlas von Bayern
The Historical Atlas of Bavaria (HAB) is a historical atlas composed of individual volumes and documents the ownership, rule and administration of all organisational levels in present-day Bavaria from early history to the present day as a historical-topographical description of the country. The volumes of this project mainly contain texts, statistics and maps. Not all atlas volumes have been published yet.
But some of them are online, especially the older ones.
There is quite a nice tool provided by the state of Bavaria here:
example using timetravel mode and topic "Verwaltungsgrenzen - Gemeinden, Verwaltungsgemeinschaften, gemeindefreie Gebiete":
But do note that the borders are just the now valid ones:
Small bit of Landkreis Landsberg
The former smallest Gemeinde of Beuern sits right on the new border between Greifenberg and Eresing which absorbed the territory of Beuern in 1978.
