Good eye LRF! You are correct,,,
In fact all three are pattern plates. They show multiple scroll types on each plate for display purposes.
The first one has the trigger guard attached but it didn't make it into my scan unfortunetly.
Yes #1 is a bit different from what was the normal game scene layout in an oval/circle/scroll outline.
I'm sure the engravers of that day would have said the same of the Torcoli type/mythical/dream scenes done today.
It's only natural for an engraver to pick up the style and techniques of the person they learn from.
Look at Fugger's style, compare it with Kornbrath and see similaritys. Fugger came to the US and worked with (and stayed with) Kornbrath for at least a couple of years before a falling out.
Styles develope over time and experience of course. Even health and injurys can direct them.
Beyer undoubtedly picked up some of Fuggers style (Fugger probably demanded it of him!) but then as time goes by changes occur.
My scans are admittedly poor quality, the original clippings weren't the best to begin with as I recall. If you get a chance to look over some of Beyer's work in hand, do so. The quality is excellent and the style(s) are almost always a continuation of some of those classics used by Fugger, Kornbrath, Bruehl, Griebel and others from that time.
