Well, 2 looks like it was picked up at the OK Gift Shop in Banff, along with a jade carving, some amorite, boxed smoked salmon and a couple T-shirts.
3 looks like a paint by numbers sketch that hasn't been painted in.
4, with cattle so close to the derrick, may conger up images of BSE. Plus, flower wouldn't grow that close to a derrick!
1 can't be treated as an Edmonton/Oilers symbol because a) You can see the mountains and b)Those safistickted Edmontonians
ain't horse riding fellers like us hicks down in Calllgary.
Plus, it looks like an active producing well...Oilers have been dormant/capped/shut in for the last 2 years.
