I was caught once by this trick, and quite handily too. A seller, who shall remain nameless and who has since disappeared from eBay after, I suspect, wreaking much havoc, knowingly or unknowingly placed some Cape of Good Hope triangles on eBay, all nicely set out on a page from an old album. I don't know if it was intentional on the part of the seller, or if the stamps had been represented to the seller as being genuine by someone else, but in any case, since I had picked up the odd item (of lesser value) from the same seller before, I bid (up to a fair amount) and won. The stamps which arrived still on the page were patently forgeries, and unfortunately, not even very good ones, which made me feel a bit of a dill. The seller had an "as is" policy and would not take them back, claiming to know little or nothing about the stamps in question. Anyway, just beware: even though an old album page may make old stamps seem genuine, it won't always be the case. The quality of the scan is very important, obviously. This one was a normal eBay scan of a whole page from the album (meaning not very large). When buying better stamps, it is always a good idea to see each stamp up fairly close. Better sellers will show you both sides of a good stamp. Remember, what you see is not always what you get. I learned the hard way.
