Don Quixote By Cervantes, Caxton Edition

I found this wonderfully old book in a friends attic and it is in really good condition considering it's age. My questions regarding this book are is it in fact as old as the date stamped inside says and is the fact that it is a Caxton edition of any significance? I researched and found a man named William Caxton who was known for his printing press and printing numerous classic books but he was present during the 1400's and the date on the inside of this book says 1890. So I'm not sure if it's from the same guy or not. The book is in really good condition with no signs of water damage or rot. The binding does have some wear and a few minor rips thoughout the book. The inside page states this is a translation by Charles Jarvis, ESQ and was published in Chicago by Donohue, Henneberry & Co with address of 407-425 Dearborn Street and the date 1890 underneath. I see no other copyright dates or publishing dates anywhere in the book. There is some handwritting on the inside cover by the previous owner which states "J.W West's Book Nov 9th, 1892". Any info about the rarity or importance of this particular book would be much appreciated, thanks! Ashley
