What two mementos from his past does Gatsby share with Nick to prove that he is who he claims to be? Why does this matter to Gatsby?

In F. Scott Fitzgerald's "The Great Gatsby," Jay Gatsby shares two significant mementos from his past with Nick Carraway to prove his identity:

1. A World War I Medal: Gatsby shows Nick a medal he received during his time serving in the war. This medal represents not only his military service but also his connection to the past and his personal ambition.

2. A Photograph from Oxford: Gatsby displays a photograph of himself at Oxford University, which he claims is proof of his education. This photo signifies his efforts to reinvent himself and achieve the status he desires.

Importance to Gatsby

This matters to Gatsby for several reasons:

1. Validation of Identity: Gatsby is often scrutinized by others regarding his wealth and background. By showing these mementos, he seeks validation of his identity and the legitimacy of his past.

2. Connection to Daisy: Gatsby’s past is intricately tied to Daisy Buchanan, his love interest. By proving that he is who he claims to be, he hopes to rekindle their relationship and demonstrate that he has transformed himself into a man worthy of her love.

3. The American Dream: Gatsby's drive to prove himself and showcase his achievements reflects his belief in the American Dream—that anyone can achieve their desires through hard work and determination.

In summary, the mementos serve not just as proof of his past but also as a means to reinforce his aspirations and dreams, particularly his desire to reconnect with Daisy.
