Friend found this cool sign, not likely interested in selling, but wondering if anybody has appraisal estimates? I can't find anything else like it.

Not sure how many American collectors we've had on the site, to help answer your question.

Mick the Kooky Moose hunting Canadian, might be the best bet ?

Well you won't find many others as there probably weren't many made, might have been a handful perhaps. Value is dependent on appeal and condition, rarity too to some extent anyway, I'd think it might be worth 50 to 100 bucks.
