Last night while going thru all my tackle boxes, some that I haven't seen the inside of for yrs,  I came across some OLD lures.  One in particular is a what appears to me a 6"  hand carved double bodied green with yellow spot lure.  Would I be crazy for fishing it or should it be hanging on the wall somewhere ?

How's the lure condition? If it's in good shape I'd upload an image and see if its worth anything. If it's in bad shape just fish it.

Post a picture, someone can very likely ID it and get you a better idea if you should fish it or hold onto it.

Bring on the lure porn. Like others have said already depending on the condition of the hardware it could be fished, but depending on the value it might not be wise.
