J. R. Sinclair’s Alice in Wonderland (Circa 1900’s), is one of the earliest illustrated publications of the book. Unfortunately, I can’t find anything about this illustrator. The style is early 1900’s, I know very little about illustration methods, I think some of the illustrations in this book were originally made as etchings.
I have the first edition of this rare book, in an ok condition, the pages are rather yellowed. I find the illustrations themselves rather charming. Let’s dive into the book, I’ll place the illustrations in order of appearence. 
Front cover with 3 scenes from the book, Alice and the gardners, Alice listening to the mouse’s tale, and Alice going after the White rabbit. How wonderful is this cover?

The Knave of Hearts, carrying the King’s crown on a crimson velvet cushion. Part of what I love about collecting the Alice in Wonderland books by illustrators, is finding illustrations like this one, which isn’t very common. Most illustrators of Alice, go for the same scenes (caterpillar, mad tea party, Cheshire cat, etc). I find illustrations like this one, that one illustrator picks out, and many others don’t, quite charming

J. R. Sinclair also illustrated the famous science-fiction author H. G. Wells’ “Little Armies”. I found some more of his graphics here: https://www.meisterdrucke.com/k%C3%BCnstler/J.-R.-Sinclair.html
I was not aware of that. Thank you. I’m actually reading H. G. Wells at the moment. A collection of his short stories. That’s after struggling a bit with “War of the Worlds” that was slightly boring.
