This was a course schedule for Harold Hayashi at age 12 with a note stamped on it that read: "transfer 4011 - 4/27/1942 evacuation". Harold's schedule was abruptly cut off because of his family's relocation orders to go to Tanforan Assembly Center.
The same day, Margaret Hayashi sent a letter to her son's teacher. The letter requests Harold's records because of their imminent move to Tanforan Assembly Center in the spring of 1942. They were later moved to the Topaz Relocation Center.
Following the events of the Japanese Attack on Pearl Harbor on December 1, 1942, President Franklin Roosevelt signed Executive Order 9066, which declared the west coast a military zone and that persons who posed a threat to national security could be excluded from this zone. These people were those of Japanese ancestry; they were forcibly relocated to the Assembly Centers and then prison camps for the duration of World War II.
Harold Hayashi was in seventh grade at the time he was forced to move with his family to Tanforan Assembly Center. Margaret Hayashi notified Mr. Hayes that her family had received the evacuation order and that Harold would leave school that day to help her pack until they had to leave several days later. Margaret Hayashi also requested Harold's academic records so that Harold could attend school at the prison camp.
The course schedule marks the day Harold left school to go to the assembly center.

As early as 1952, the Friden Calculating Machine Company produced a calculating machine that would find the square root of a number entered by simply pushing a key. In 1962 the firm introduced this machine, which would find squares of numbers as well as square roots. It was manufactured until 1965.
The full-keyboard electric non-printing stepped drum calculating machine has a metal frame painted tan and ten columns of light tan and brown plastic number keys, with a brown key at the bottom of each column. The keys at the bottom of the columns are numbered, from left to right, 0 9 9 8 8 7 7 6 6 5 5. These keys are used to set the decimal point in a number whose root is to be taken, and to begin the taking of the root. Metal rods between the columns of keys and under the keyboard turn to indicate decimal places in ordinary arithmetic.
On the right are two columns of function bars. On the left is a register for recording multipliers, with nine light tan keys and a zero bar for entering numbers. Around these keys are three levers and four function keys.
Behind the number keys is a movable carriage with an 11-digit revolution register and a 21-digit result register. White plastic buttons above the result register rotate to set up numbers. Ten numbered buttons are under the revolution register, spaced between the digits. The clearing button is marked C. Zeroing knobs for the registers are on the right of the carriage. All three registers have sliding decimal markers. The base of the machine is covered with fiber. It has a black cord.
The sides, back, and front of the machine are marked: FRIDEN. Above this mark is a square-root sign. A superscript 2 is to the right of it. A mark on the bottom reads: MODEL [/] SRQ 10. Another mark there reads: SERIAL S2000. The serial number under the word SERIAL has been effaced.
Miss Piggy is a hand-rod puppet originally performed by Frank Oz and currently performed by Eric Jacobson. In a hand-rod puppet, like Miss Piggy, the performer’s dominant hand goes into the puppet’s head and operates the mouth and sometimes other facial features. The less dominant hand controls the arm rods, which are thin rods connected to the puppet’s hands. Miss Piggy is a diva pig who believes she is a superstar. She is madly in love with Kermit the Frog and is an expert in karate. Miss Piggy began as “Piggy Lee” on The Tonight Show in 1974 and eventually the “Lee” was dropped so as not to upset Peggy Lee. Miss Piggy then became a major character on The Muppet Show. This specific puppet was created for display at the National Museum of American History in 2016.
