SchwalbeUnisex's AV13 Inner Tube, Black, 26 x 1.50, Pack of 2

Do these have schrader valve stems? I want to be sure the photo matches the product.

Misleading information: 2- 26 x 1.5”; however on description below it says: 1-26 x 1.5” and 1- 26 x 2.25. What is correct?

What range of widths does it fit? Is 1.5" the max or min? Thanks.

Would these fit a 26 x 1 3/8 tire? Have an old Raleigh Sports, and it’s hard to tell from the range on the Schwalbe packaging whether these would fit
