It was one of those strange periods when I didn't have a record player (visiting my dad in SoCal - a great place to be when "Sgt. Pepper's...' was released), but I did have a reel-to-reel, and I got those two albums.
I just took a look and The Beatles albums were put out in that format straight through to 'Abbey Road' - odd but true. Maybe this was a popular format outside the U.S. Dunno.
Anyway, prices on Ebay range from $50 on up to a few hundred. Interesting.
