Perhaps another aspect of this is the introduction of the tear off
bottle seal, and the twist top crown seal, both of which are post 1980s
introductions, so combined with the pull tabs, (and possibly lever off
crown seals before them) they might provide an almost continuous
typology for most f the 20th century (and 21st to date).

I remember the South article, in American Antiquity, I believe, part of
a series organized by Binford on home to observe normative patterns of
behavior at short-occupation sites, hence the pull tab counts at modern
hunters' camp sites.

I think South also mentioned the existence of pull tabs as an excellent
example of the horizon phenomenon, which it certainly is--they have a
known date (1963) and point of inception, as detailed in these posts,
they spread very rapidly, were ubiquitous, and then disappeared
rapidly--one of the fattest battleships ever.  Being made of aluminum,
they constitute a marker for "1963 to c. 1985" (I'm closing them out in
1985 based upon personal observation--I know a few are still out there,
but they were no longer present in number sufficient to support the
horizon after that date).  A thousand years from now, our remote
professional posterity will hit the "pull tab level," and know that they
are looking at US.

Subject: Pull Tab Typology

Hello,

A colleague mentioned a pull tab typology that could be used to identify
the brand of beer or soda pop based on the pull tab, but couldn't recall
the source.  I was curious if this was something out of can collector
circles or maybe out of something like Rathje's garbage project.  Does
anyone have any insight or know of any references on the subject?

Thanks in advance,

Sean
