Since precision is important: no, there were not swastikas. There was a symbol of an eagle (the Reichsadler) over an 'iron cross' symbol as part of the advertising. You can find that fairly easily by looking at an image search on your favorite search engine.

n.b. the iron cross symbol is still used in Germany for e.g. the roundel of the German Air Force.

I don't doubt that the design would fall afoul of the MS content guidelines as I'm sure perching the Reichsadler on top of the iron cross would be the kind of thing they mean by "contextual clues".
