Those pictures aren't the same snake. This one has two dots at the beginning of the neck stripe. One dot Is centered, the other to the snakes left. Which would be visible in that second pic. I circled area to look at difference. It also has a "slice" on the edge of the neckstripe that the other doesn't have. And the head isn't blushed.
Next, one dot, centered, no slice, and blushed head.
And, the end of the neck stripe Is different as well. Who are you looking to buy this snake from?
