please add edition

[Kathryn]

I tried to add this myself, but it wouldn't let me since it shares an ISBN with a different printing

Agatha Christie
The Mystery of the Blue Train

ISBN - 0671810138
there is another edition with this ISBN but it's a different one, published in 1982:
https://www.goodreads.com/book/show/3...

paperback
published by Pocket Books
36th printing, December 1976
226 pages

I have a photo of the cover, but don't know how to attach it here for you. The cover is almost identical to the 1982 printing, but without the cameo of Poirot at top, and says “AUTHOR OF CURTAIN” in smaller print between “Agatha” and “Christie”, price is $1.75, not $2.95

Thanks so much!

bumping for a more experienced librarian:

Issue: should this be added as an alternate cover edition?
