On the rounded (or "cropped") vs. square corner issue, my recollection is that the dating here is based on Ted Z's having posted about his childhood memories of getting the rounded ones from loaves of bread that his family purchased for their restaurant(s) back in 1947 in conjunction with his having no memory of having seen the square corner ones pop up until more recent years.
