This handsomely aged bit of ephemera is from the 1911-12 Tucumcari public school year. Back then, the best grade was an E, the worst was a P, and you needed an overall average of 80% or above to move up to the next grade.
Today we have a bit of ephemera from the high school in Belen, New Mexico - a student's registration card from 1937. The front of the card shows the student's name, address, & her parent's occupations: father unemployed (tactfully left blank), mother comptometer operator. The back of the card shows her teachers and schedule.
