leonWelcome to armpit collecting 
. It's the backbone of the hobby !!.
For the record I have seen one other blue background Old Put card besides this one and mine.....they are rare though....almost all are of the red background variety....
edited to add that I am glad to see this one be a non-hof'er. For some reason the great majority, that I have seen, seem to be HOF'ers...
