Leaf Curl

[Hairy Moose Knuckles]

This is strange. At least it's strange to me. I'm not new to growing tomatoes. Has anyone seen this phenomenon? This tomato is from seeds that I saved several years ago. Parent plant was healthy and prolific.

This plant has been this way since day one. I have 160 plants, but only 1 looks like this. It appears healthy. I haven't been able to repot like I normally would, but like I said it's looked funny since it came up.
