Deltiology (from Greek δελτίον, deltion, diminuitive of δέλτος, deltos, "tablet, letter"; and -λογία, -logia) is the study and collection of postcards. Compared to philately, the iden- tification of a postcard's place and time of production can often be an impossible task because postcards, unlike stamps, are produced in a decentralised, unregulated manner. For this reason, some collectors choose to limit their acquisitions to cards by specific artists and publishers, or by time and location.

069 - Romania

Peak Bucsoiu has 2492 m altitude. It is the second peak of the Bucegi Mountains, being exceeded only by Omu, 2507 m.
In topography, a summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. Mathematically, a summit is a local maximum in elevation. The topographic terms "acme", "apex", "peak", "summit", and "zenith" are synonyms.
The term "summit" is generally only used for a mountain peak with some significant amount of topographic prominence or topographic isolation (distance from the nearest point of higher elevation); for example, a boulder next to the main summit of a mountain is not considered a summit. Summits near a higher peak, with some prominence or isolation, but not reaching a certain cutoff value for these quantities, are often considered subsummits (or subpeaks) of the higher peak, and are considered as part of the same mountain.
A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top.
