Why Track This
The mark that makes every one of the 75 catalogued bottle/jar types in this collection identifiable as Three Rivers glass — the single most important piece of physical evidence for attribution.
Current State
Per Michael David Smith’s book, the logo generally appears on the bottom of a bottle/jar or on the side near the base; the “3R” + star variant is always on the bottom. Some side-marked examples are worn and require a strong light to read. The trademark also appears independently corroborated in Julian Harrison Toulouse’s Fruit Jars collector reference.
Next Action
None.
Notes
Cross-reference: every record in the bottle/jar artifact catalog under inventory/items/ bears this mark.
