Yes, our catalogue covers initially were fantastic, no idea who did the art but there were superb, Atarimania has some scans of the catalogues, I myself only have what they have, I tended not to collect the catalogues as I worked for them in London, bloody things were every where in the stock room
We had a Tandy opposite that wanted me to join them as a manager but no ta, awful company that were just uneducated box shifters, Maplin have semi morphed in to a Tandy variant where they have extended their range of over expensive tat and trust me it was tat. Roger the director used to fly to the far East on stock trips and basically if he got a good deal we stocked it. One of the things he brought in was a range of remote control cars and a boat which were shown off at a managers meeting, the cars were fragile rubbish and genuinely, the boat sank, seriously...
It was fun for us managers until we had to sell this stuff..
Last I heard they were taken over by a German bank and from my rare visits to the shops the epic tat sale continues as do thee staff who bar the odd one who know little about electronics let alone the guff they sell, at least my guys bar one all had electronics qualifications..
