Postcard: Long-finned fish

This one is a couple years old, and has been in the backlog bag since it was returned to us.  (This is part of the reason I resisted starting a blog when the girl first suggested it; it adds another layer to this project I wasn't sure I wanted to deal with.  But it's been nice having this record, so I'll just carry on.)

The boys aren't sure whose this is, but I'm saying it's Jonno's because of the handwriting. 

There is no note from the finder on this one.  It took six months for it to be returned.
