This is probably the most atypical Oregon City Woolen Mills blanket I’ve ever encountered and the only example of this pattern I’ve ever seen. It bears the very first OC label so I would date it c. 1905-1911.

The design looks Scandinavian with its snowflake motif and I can’t recall seeing a pattern from any company remotely like it.  Of course, at my age I don’t recall brushing my teeth this morning so don’t go by me.
