Start with a catchy graphic-
T206 - L@@k!!!
Begin with an element of discovery-
I found these old tobacco cards in my grandpa's [attic] [barn] [shoebox] [cigar box] [Bible].
[Feel free to use liberal spelling variations, particularly for tabbaca, tobbaco, tabaco....]
Insert an internally contradictory disclaimer-
I don't know nothing about them but I'm told they're real rare and real valuable.
Provide plausible reason for selling cards, dwelling on touching medical tragedy or economic hardship, paying no mind to remarkable coincidence between recent discovery and event necessitating sale (select one)-
I'm only selling these so I can buy my wife's medicine so as she don't die.
I need me an operation that's why I'm offering them to you.
#$&# bank is foreclosing.
Need to raise money for my son's bail.
Include speculative statement alluding to long-term appreciation-
They're not making any more of these.
They'll only get more valuable.
These cards are hard to find anywhere.
Conclude with another disclaimer-
Don't bother asking no questions since I don't know nothing about these.
Be sure you have less than five prior eBay transactions-
100% positive feedback!
Insert blurry photo/scan of card. In the unlikely event you decided to include a back scan, be sure to create realistic looking paper loss eliminating pesky reprint language.
Congratulations - you have a winner.
