Dave SNot all Bond have clipped corners, some are squared. Measurements the seller lists are correct and they were blank-backed. Keep in mind that Bond had different formats, i.e. "homogenized" (which this would be)came in the bread, "exhibits" were sold in arcade machines and were a bit bigger, and the "premiums" were much larger.
The "homogenized" were widely re-printed but I believe this one looks real.
