The posters are part of the IGTO’s Think.Israel campaign, appear to show the occupied territories of Gaza and the West Bank within Israel's borders.
The IGTO made the decision to pull the posters from the sites after both the Palestine Solidarity Campaign and Dan Judelson of Jews for Justice for Palestinians complained about the map for being misleading and unnecessarily political.
The posters feature on 108 sites across the London Underground network with a further 42 that had been due to go up.
The IGTO is considering producing a new poster, without the map, to replace the existing one.
The ASA has yet to make a ruling on the posters, but is currently investigating the complaints and expects to have an adjudication in the next few weeks.
