This is a fun one.  The card is 8.5" x 11" and is part of a set of four made in the 1960s and handed out by the Roddenberrys with a letterhead greeting.  Unfortunately, all I have is the one card.  

YES, I COMBINE SHIPPING!  

1. IF YOU WANT MORE THAN ONE ITEM AND THEY ARE BUY IT NOW, PLEASE PUT THEM INTO YOUR CART AND ASK FOR A COMBINED INVOICE ON CHECKOUT, AND I WILL SEND YOU A DISCOUNTED SHIPPING INVOICE.  IF YOU DO NOT DO THIS I CANNOT GIVE YOU THE DISCOUNT BECAUSE IT IS AN ADMINISTRATIVE NIGHTMARE FOR ME TO ISSUE PARTIAL REFUNDS.  
2. IF YOU ARE BIDDING ON SEVERAL AUCTIONS, PLEASE FEEL FREE TO WAIT TO PAY THE CLOSE OF ALL AUCTIONS ENDING THE SAME WEEKEND; JUST SEND ME A PM LETTING ME KNOW WHAT YOU ARE DOING.  I WILL SEND YOU A COMBINED INVOICE FOR WHAT YOU WIN.  
3. PLEASE DO NOT TRY TO WAIT FOR ANOTHER WEEK'S AUCTIONS TO CLOSE; DELAY OF MORE THAN A FEW DAYS FOR PAYMENT WILL TRIGGER AN UNPAID INVOICE CASE.  

The Fine Print:

1.  Please don't contact me directly with any offers; the minimum bid or BIN is the least I will take.   

2.  I do not end listings early.  

3.  I do not ship internationally via another method than what I've specified; you will have to pay for shipping as calculated by eBay.  

4.  I don't control the sales taxes applied to your purchase and I cannot remove it.  

5.  The photos are part of the description of the item.  Learn them, know them, live them.
