Here's a classic example of a Sevans models ad from the mid '80s. This was featured in several issues of DWM (Doctor Who Monthly) in 1985. I remember drooling over this particular ad for a long time as an 11/12 year old before finally getting one delivered to me by Santa in 1986. As you can see, the price was £11.95. That sounds so cheap by today's standards! It's amazing how inflation creates that impression... probably the equivalent of £30-£35 nowadays I guess. Thanks to Outpost Gallifreyan, John Main for emailing this in.
