New Yorkers boarding buses and subway trains were surprised with a wall of Axis Powers propaganda, courtesy of Amazon, on Monday.

The e-commerce giant is promoting its new show Man in the High Castle — an alternate-history period piece that takes place in an America ruled by Nazi Germany and imperial Japan — by blanketing symbols of the two fascist governments across buses, subway trains and online ads, as first reported by Gothamist.

While the company seems to have stopped short of plastering actual swastikas around New York's public transportation system — at least from the pictures Mashable has seen of the ads — the campaign prominently features an emblem that resembles the Nazi iron cross within an American Flag as well as well as a variation of the Rising Sun flag used by the World War II-era Japanese empire.

An ad on the outside of a bus shows a Manhattan street draped with Nazi flags. Another online shows the Statue of Liberty giving a Nazi salute.

If Amazon's goal was to grab people's attention, it certainly seems to have succeeded. Twitter users were perplexed and more than a little put off by the company's choice to advertise using the insignia of governments that conspired to kill millions less than a century ago.

I get that they're promoting a tv show, but that subway car decked out in Nazi German and Imperial Japanese imagery really creeps me out. — Black Pete (@EtepKcalb) November 18, 2015

i don't know how to feel about amazon having an ad budget to cover subway trains in nazi imagery. — BOMB-ASS PINOT (@spumantecarlo) November 20, 2015

I would feel uncomfortable sitting in a subway car with the American flag emblazoned all over it, let alone a Nazi symbol. — Dan Connor (@thestereobus) November 23, 2015

Going to Amazon and being greeted by a Statue of Liberty doing a Nazi salute sure is a thing I don't get more used to over time. — Sarah W. (@toasterposey) November 21, 2015

Woah, the Statue of Liberty giving the Nazi salute had me really confused on Amazon for a second. Then the ad text scrolled. — Mike Majeski (@mmajeski06) November 20, 2015

I know it's fictional but f*ck. Subway cars wrapped in This show. No. @MTA — stacey agdern (@nystacey) November 21, 2015

Honestly, Amazon, I understand you want to promote The Man in the High Castle, but finding your home page full of Nazi imagery is offensive. — Cora Buhlert (@CoraBuhlert) November 23, 2015

I know it's an ad, but going to Amazon and seeing Nazi propaganda is still really jarring. — Melody Burst (@MelodyBurst) November 20, 2015

Amazon did not immediately respond to Mashable's request for comment.
