Vintage Prints 3 cityscape cobbler man vatican and gondolas Type and signature Help Thanks

cobbler rag man print Actual Size is 9 3/4" X 13 5/8" looks like an R with 2 tt in the middle.

the Vatican and gondolas framed size is 15 1/2" X 18 1/2" What are those black lines because this one has no glass protection. How was the color added?

The Cityscape print's incised plate measurement is 10 1/2" X 13" E Jacobis

The first is a lithograph and the following two I believe to be Intaglio prints

 

The last one is E Jacobi. For Emil Jacobi.

 

The one of Venice is the only one worth anything substantial.
It is an etching by Hans Figura.

I have a few of his pieces, sometimes he prints on silk as well as paper.

 

The Vatican is not in Venice. St. Mark's, perhaps?

 

The first one is a lithograph by Seymour Rosenthal: "Street Vendor".

 

The first one reminds me of the very small town near where I was raised.
We had a 'rag picker' who was a Jewish immigrant and pushed a cart around town collecting anything anyone was throwing away. Unknown to a lot of people, he had 3 sons who he put thru college (Penn) and a daughter who died when she was 18. He was crushed as she was the apple of his heart.
To complete this story, the 3 sons carried on their father's business on a much larger scale becoming junk dealers in major each coast city - now called recyclers!

 

The first one reminds me of a can vendor from near that I helped up a street with an incline with his mountain of cans. That was a rewarding experience to meet this proud, hard-working, determined, individual with his mountain of cans. Thanks Pat, that does look like the church.

Is the color done with the aquatint Process on this one?

 

I have 2 Figura prints and I don't know how the color was done. It looks like wood block to me, which is possible - some relief process. Easily could be wrong.

 

Here's a detail from one of my prints:


That could be aquatint, but there seems to me to be some kind of color registration thing going on and I don't know how that would be achieved.

 

Here are some enlarged images there is overlap color combination MOS. Are those poles or what?

 

Apparently those are mooring poles for gondolas. I think the prints are an etching/aquatint combination, but I don't know how the color was added.
