Featured Blue Opaline Glass Pitcher

I don't think I've ever seen a pitcher with this wide foot rim. It's 6" tall and holds a bit over 1 quart. The underside shows a lot of shelf wear around the rim. I'd love your thoughts on age, origin, etc?

Thanks!

here's one with marks (haven't heard of this one before...)

Blue Opaline Glass Pitcher Orth MFG company Wisconsin | #153391723 (worthpoint.com)

 

Stunning. Be still my heart. That color is wow!

 

Orth is not name I've heard before.

 

This is the closest item I could find with the same color. Probably doesn't help much.
This isn't my listing.

I’m probably way off base, but with that WIDE base, makes me think it could have come off of a ship or cruise line....it’s NOT about to tip over!!!!

 

Thank you! Certainly appears to be the same pitcher, though mine isn't marked. Most of what I've found on Milwaukee glass companies are those that made beer and medicine bottles. I haven't found anything on Orth Manufacturing Company.
