The PSI was rather unusual among mainstream socialist/social-democratic parties in Europe in using the hammer and sickle as its symbol. However, the symbolism of the party was gradually moderated. In 1978 Craxi decided to change the party logo of the party. He chose a red carnation to represent the new course of the party, in honour of the Carnation Revolution in Portugal. The party shrank the size of the old hammer and sickle in the lower part of the symbol. It was eventually eliminated altogether in 1987.
