Harry Potter variant

Harry Potter and The Chamber of Secrets, octavo hardcover w/full dj published by Scholastic Press 1999, First U.S. edition. Three-quarter green cloth w/diamond imprinted blue boards and silver lettering on spine. Minor foxing to the dj interior and the binding is cocked.  Variances begin under Also By J.K. Rowling on the verso of the title page with the misspelling of Sorceror's.  Neither the dj or boards have Year 2  badges and the bar code on the dj rear is printed at a slant, mid way up the left side, ending w/the numbers "51795".  The last word of the last sentence on pg. 332 is ancestor instead of descendent.  These faults align with the Issue/State points understood to precede the trade First edition.
