I'd advise people not to get their credential from Salamanca.
At first glance it appear clever, but each box has the name of a stage. If you deviate from their suggested stages, split stages (as i did with today's 35km stage) or double up you'll end up with blank boxes and/or no place for the stamp.
Their solution is the reverse side has a large blank page for "other stamps" although I usually asked albergues to stamp a blank area on the front or just stamp a wrong box.
