Deltiologist and deckled
I like it.
I foresee early pictorial postcards prices going
through the roof in the next 100 years.
Western Australian PPC's are already around $25 each
for historical style.

This article is about the practice of collecting postcards. For postcards themselves, see Postcard.
A postcard collectionDeltiology (from Greek , deltion, diminutive of äÝëôïò, deltos, "writing tablet, letter"; and -ëïãßá, -logia) is the study and collection of postcards. Compared to philately, the identification 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.
Deckled:
In manual papermaking, a deckle is a removable wooden frame or "fence" placed into a mould to keep the paper slurry within bounds and to control the size of the sheet produced. After the mold is dipped into a vat of paper slurry, excess water is drained off and the deckle is removed and the mold shaken or "couched" to set the fibers of the paper. Some of the paper slurry passes under the deckle and forms an irregular, thin edge. Paper with a feathered or soft edge is described as having a "deckled" edge, in contrast with a cut edge.[1]
Machine made paper may artificially have its edges produced to resemble a deckle edge. This is most commonly used for private presses or fancy stationery.[2]
