On the right is a small sheet featuring the town of Miranda del Castañar in Salamanca. It's from a 2021 set featuring "charming towns". And on the left is a stamp commemorating the The Federation of European Philatelic Associations (FEPA) Youth Exhibition "Juvenia" held in Avilés in 2017. Below that is a stamp featuring "jet" which is an organic carbon gemstone. This stamp actually has traces of jet from the Asturias region in northwest Spain, stuck to its surface.
