Archaeological evidence from across the Roman world has dug up trinkets from various other parts of the world; Jewellery, figurines, carvings, etc. Basically they found everything but fridge magnets, keyrings and postcards. Not only did Romans have a penchant for travelling the world – sometimes for leisure, sometimes for education and sometimes because they had to because they were soldiers – but they also liked to bring back trinkets for their families. Roman-era tourist tat actually existed.
