Here are some pics. Thanks to anyone who can help identify origin, date, style, etc...

Welcome to the forum. The trademark on your spoon looks like one that was used by International. The issue date for the pattern might give a rough idea of when your spoon was being sold, but at least for myself, a full image of the handle will be necessary to attempt an identification.

Oops! I just noticed the complete handle is viewable. The pattern looks like it is LaRochelle which was issued in 1909. I cannot tell you when production stopped, but hopefully, someone else can.

Thank you, Silverly!
