The plays and poems of William Shakespeare complete in 13 volumes

I have the 13 volume cloth bound, with gold lettering on the spine. There is no publication date, but it was in a matching cloth covered box. The books are mint with natural yellowing of pages. No water marks etc. The box is not in good condition. I would like to know the publication date. I note that that George Routledge printed 2 editions, but I don't know which edition this was. The books are about 3 1/2 x 5 1/2. It was originally sold by Stoll and Thayer Bookseller of LA. I would guess the set is more than 100 years old.
