I didn't know Latin also venerates icon
They do. Last decades there's revivial of true icon in Roman Catholicism, after centuries of worshiping images (plus a few icons of the Theotokos), that started in Renessance. This revival is connected with a few things, probaly new technologies (=discovering Eastern Christianity), neocatechumenal way, maybe some thoughts of Vaticanum Secundum.
However, I think that e.g in Poland thanks to the huge Orthodox population there Latins were more aware of icons, especially that our Lady of Częstochowa - the most beloved Theotokos' image by Poles - is in fact an Orthodox icon.
