Yep, those are the ones. I was just looking at the Belgian ones last night (as I continue my quest to deconstruct the old Minkus and Harris ablums).
I shouldn't have blamed the stamps, entirely for my boredom. The blame probably rests more on the bag sellers, e.g., Mystic, Harris, etc. The stamps themselves are not horrible (but they aren't at the top of the heap aesthetically either). But, as a kid, eagerly awaiting the discovery of some new treasure, and instead finding the 10th Franco in the same color - this can leave you scarred a bit for life.

I'm joking, but then again, this is probably a factor in why Spain and Belgium are at the bottom of my list of European countries to collect. It doesn't help that Franco looks a little ticked off (and smug at the same time) in the portrait.
Just noticed, but King Baudouin looks like one of my older brothers when he was in high school.
