Wow, great story! Almost uncanny.
I think there are multiple methods of reproducing prints. Not all of them would be revealed by dots.
Evidently Claude was painting and teaching art up unit the end in 2015. Your rendering of a boy on a tractor seeks to tap into the nostalgia market; his clothing looks like 1890-1920 but of course the original was painted much later, quite possibly in the 21st century.
I couldn't find this particular work on the internet, but his others seem to be in this same pastoral vein. I did see portraits of cows, canned/bottled fruit and flowers. These would appeal to those who would like a kinder, gentler Norman Rockwell.
His unframed prints seem to go for about $20.00. Framed, maybe $40-60. Was the one at the top of the stairs in your Grandma's Victorian house an original? Was it ever reproduced that you know of? If it was an original, it would be worth more, possibly into the hundreds. Schneider's work seems to be widely reproduced and can even be purchased as greeting cards.
This may be the obituary you found:
"The 15th of April 2015 marked the unexpected passing of Claude Schneider of Jonas Ridge who expired peacefully in his home. He was born April 12, 1932, in Wisconsin Rapids, Wis., to the late Joseph F. Schneider Sr. and Cayrl Cooley Schneider. He graduated Port Edwards High School in Wisconsin, and achieved a degree from Layton School of Arts in Milwaukee, Wis.
Claude was a lifetime artist. In his earlier years he worked in furniture sales, then as a fine artist for various companies throughout his career and was a contributor for the High Point furniture market until retirement. God blessed him with talent in his hands, and he continued to paint pastel pictures and build frames in his home-based “Time Ago Again” studio while he taught art classes at Land Harbor Resort. He was involved in Jonas Ridge Volunteer Fire Department, Ruritans and was a volunteer for Meals on Wheels. He attended Crossnore Presbyterian Church and loved his church family. He enjoyed entertaining his family and giving his grandchildren art lessons.
His hobbies were art, illustrating children’s books, collecting antiques, woodworking and bird watching."
