Truly Flowing Blue Pitcher ID???????

There's a small but very decent antique store a couple miles from where I currently recline. It's not worth going to weekly, as they don't get enough new stuff for me to visit it weekly (but, mind you, it's far from stagnant), but I enjoy going more than I would as I enjoy talking to the female owner (the male owner does not seem to like me much?)

She's one of the few people I've told in my city, that I'm gay, as I felt comfortable enough to tell her in a joking manner once as we were laughing at something pertaining to a postcard of an 'attractive'(?) woman.

Anyway, I've always admired this little (compared to normal size) pitcher and decided I'd pick it up. I had always left it behind before as it has so much 'crazing' in its glaze, but is otherwise little damaged.

She told me, "You can just have it," as she likes talking to me and wanted me to have a gift (if I remember, she said she had it in her kitchen for 30 years). I couldn't accept that and shot down the idea of it, in which case she insisted she can give me things if she wants to (she's strong in the head).

I boldly, jokingly, commented back, "And I can buy things if I want to. I'm a big boy now" (she's known me since I was a late teen).

Shaking her head and smiling, she told me she'd charge only $5, as it was going to be enjoyed in a good home. I agreed to this, and we headed up to the register where I asked, "Can you break a 10?"

She told me she could, took the bill, and attempted to put two $5 bills together and hand me them-- the sly devil she!

I laughed and tossed one of the fives back at her. "Nice try."

As usual, I didn't have her wrap or bag it, as my car seats are inclined and padded (and I'm a very good driver unlike the idiot yesterday who pulled out in front of me onto a road where it's 55 MPH, in which case I had to slam on the breaks and swerve-- having 10 minutes before gotten my car out of the shop!! And he beeped his horn back at me, the dumby!)

The pitcher is truly a flow blue-- so flow, that it still looks flowing! The maker over-did it with the glaze so that, I assume, it looked almost kitsch in its day. Perhaps the overdone cheapness of it was intended? I know not.

In fact, I know nothing on it. It's just a big stand-out, and goes good with 'blueware' (I need a blue porcelain cup, though) and flow blue.

So, I'm hoping for an:
age
manufacturer
pattern?
