Morihei Ueshiba's kyoju dairi (assistant instructor) certificate in Daito-ryu Aikijujitsu.
It is in Sokaku Takeda's handwriting and says:

1. When accepting students for instruction in Daito-ryu aikijujitsu be careful to choose persons of good conduct.

2. When instructing students, have them write their address, name, age, location of their dojo, and the terms of their instruction in an enrollment book and have them stamp it with their seal by way of authentification.

3. When instructing students, an initial payment of three yen should be made to Takeda Dai-Sensei as an enrollment fee.
