Yeah so the account Henry Martinez was created in December 2023. Its not certain whether the banner image was the same since the account was created or recently changed, I dont believe there are ways to track that without manually archiving the account which nobody knew about it before Cole Allen. But the Henry Martinez posted a single tweet the same month the account was created simply posting "Cole Allen". The banner image is from the website Time Machine posted in 2022, which seems to have the Trump assassination photo from July 2024 superimposed into it.
