Democrats raised more than $4,000 to set the "Trump Baby" blimp in the air during the president's rally.
Museum of London Director Sharon Ament said the museum is in "strong dialogue" with Trump Baby's creators to install the blimp in its permanent protest collection.
The blimp of President Donald Trump in a diaper was a feature of protests during his visit last year.
"I'm tired of people disrespecting our President!" a Trump supporter stated in her now-defunct GoFundMe page.
"'Trump Baby' is really just a mascot for a much wider movement that is ready to resist," British activist Leo Murray said.
"Moral outrage is water off a duck's back to Trump," a petition for Trump Baby said. "But he really seems to hate it when people make fun of him."
