There will be a lecture on the history of bagatelle games tomorrow.
James Masters is a UK researcher and collector who will give the talk over Zoom. This is in relation to the ongoing exhibit of bagatelle games at the Field House Museum in St. Louis MO.
Pictures of the show in the above link, but here's one:
The lecture is at 2pm EST and I think the exhibit runs until the end of the year.
I might be doing a presentation with the museum in the fall. If you are interested in the question of "how did we get from table games to pinball", we have been doing lots of collaborative research to help flesh out that story.
