WW1 Trench Art 1917 German Artillery Shell Tiny

Description

Tiny little piece of trench art.  I assume that it was made by a German soldier, but really have no idea.  Headstamp
shows 1917 and 1918 dates.  Someone has scratched some initials into, maybe a WAN, but hard to make out. Only about 2 1/4" tall.
The penny is for scale and is not included in the auction.
Be sure to look at the pictures which are part of the description and ask any questions before bidding.
Payment within 3 days of auction ending and item will be shipped using USPS Retail Ground in a padded
within 3 days of payment, usually the next day.
