I have 4 pieces of signed Eric Hoglund and none of them have the 'Boda' - they're all the letter 'H' followed by a series of numbers... I've not photographed them yet but will and will post the signatures up here.
Victor, your piece compares favouably with the one in Martyn's second link - I'd say it was almost certainly Eric Hoglund. Hopefully Bill Geary (who knew Eric Hoglund) will see this and confirm for certain.
