Glass Pitcher with Sunflower - Identification Help

When I picked up this pitcher, I was surprised at the weight of 5.6 lbs. It is 9 1/4 inches tall at highest point. I loved the joyful mix of elements with a sunflower prominently displayed in the middle, the fluted top, the diamonds and squares and the lines and cross hatching. It seems to have been put together from four different sections, at least there are four seam lines. The last two photos show two of the four seams and the handle attachment. I do not know anything about glass like this. Could anyone please tell me something about it.

 

Looks like a newer piece of Imperial's D'Angelo.

The 1920s version, the flower was cut.

Look down into the bottom of the pitcher, or run your finger over the inside bottom. You're looking for the I over G mark that was used in the 60s.

 

Thank you. That's it. I never looked inside.

 

It's still a nice looking pitcher.

 

It already had a place, I just wanted to know about it.
