What is the most unusual card you have/had and who issued it?
"Unusual" is subjective. Unusual in appearance? Unusual in benefits? Unusual in degree of difficulty to obtain or "exclusivity"? Unusual as in offered elsewhere, but not here in the USA?
Many cards are unusual in appearance. Some are with benefits, offering unique perks. Some are not obtainable by us common rabble 
Some can be custom designed, so they are a "one off" type product, no one else will have the same design.

For me, it would prolly be the FNBO Amex at 6.25% V APR, together with 1.5% cashback rewards (the rare card combo where you can have both a low interest rate together with a pretty good rewards program) 
Also my grandfathered Cap1 No Hassle Miles Ultra Platinum MC with 2% cashback rewards on travel purchases, which works like a Venture -- I was also able to get AF perma-waived for it -- but which Cap1 apparently sadly no longer issues, now that the Venture has succeeded/superseded it in their product line.
