The Exhaustive and All Encompassing Categories Post-Cards and Related Experience

There are quite a number of ways of reading a post card. Vainly I will attempt to present all of them to you. Such an exercise in categorization is one of the favorite games I play with Dr. Oppermann:

1) A post card can be read hurriedly, as one has just tendered the mail.
2) A post card that is between sips of tea, seen obversely, its reverse and adress are permanently forgotten
3) Post cards of adorable Animals
4) Post cards that remind one of the Borgesian Chinese Dictionary
5) Post cards that state directly "I have nothing to say"
6) Post cards that are obliquely Chinese
7) Post cards that are insufficiently Chinese
8) Post cards that are about Seljacks, but incorporate a light-hearted impressionist theme
9) Post cards of images produced by Breugel or Durer
10) Post cards presented with other artistic images
11) Post cards of great philosophers
12) Post cards with sufficient patina
13) Post cards of concentration camps
14) Post cards of the 50 "united states" which lack patina
15) Post cards from the tavern "The Ugly Mug" featuring discourse on "decaying Brits"
16) Post cards of Bears
17) Post cards of Ravensburg
18) Post cards of Hiroshige's prints
19) ...
20) Post cards that make mention of the Bestand
21) Post cards dealing with French philosophers and ex-wives
22) Post cards alluding to a discussion of Goethe or promising a later discussion of Goethe
23) Un-marked post cards
24) Post cards that are from other people but still belong to the category of "Jan Oppermann's post cards." (i.e. Jim Gossett's heretical post cards)
25) Post cards that do not mention "I have nothing to say."
26) Post cards alluding to phrases of Bob Dylan: "the emptiness is endless/ cold as a clay/ you can always come back/ but you can't come back all the way..." for example.
27) Post cards that mention the "Arcadian"
28) Post cards that mention "nubiles" (though I am expressly forbidden to discuss nubiles)
29) Post cards that discuss Sam Beckett in some respect.
30) Post cards with otters on them.
31) "post cards showing, or alluding to, Soviet cars."
