I know it is not a PA Crappie, but you wanted to see a picture of a Crappie that is bigger than 17 inches.

Chaunc has a picture of a 17 1/4", 2lb 15oz crappie he caught at Ky Lake, over on Crappie.com's Pa board. Seen it yesterday.

I have seen pics from other states but want to see Pa 17in Crappie pics..

Wish I could give you a pic. Maybe someday. A few years ago my grandpap was strolling along Edinboro Lake when some guy just docking asked him if he wanted to see something. He said sure. The guy opened a cooler with an 18 inch crappie inside. Grandpap said it was the biggest he ever saw. They are few but out there.

That would be the trophy of all trophies. I've caught some 16" out of Lake Arthur, there are bigger ones in there I'm sure.

I'm positive I had one on in the upper lake at Herford that was every bit of 18" or bigger.  I was in my float tube, it got off as I was trying to lip it.  I never thought I'd be so disappointed over losing a crappie.  It dwarfed any other crappie I've seen.

Still,
 
I got one several years ago that was 18 1/2. Got him on the most obnoxious "lure" you could imagine. I was just goofing off, and drug it out of an old tackle box from when I was a kid. As you guessed it was old too.

I,ll send pix of the one on the wall later tonight. The wife keeps the camera in her purse, she works days. Giz, shrinkage!

Mmmm..... how about "downsizing" 

They are out there.  Pymy and Conneaut Lake have 'em.  2 years ago on the ice we caught 4 crappies off Tuttle Pt. one day that were all over 16" (whites) the largest was 16.75".  An ex girlfriend of mine caught one in the north end canal at Conneaut Lake about 4 years ago that was 17.5" (black).  The black was obviously the heaviest, I would estimate it at 2.5 to 2.75#.
