Hi Paddy,

There are actually three big MALCO identifation signs that know of.They made a 5' diameter round one that looks like the pump plate under discussion.Possibly the oldest.They also made a rectangular one,about 3'X5',with a smaller thunderbird on top above large MALCO letters.There is a pic of it in use on page 66 of the hardback book Route 66 Remembered.I like pics of signs in use when I can find them.Then,the most recent,they made a large,8',oval with just MALCO on it.Very plain.

Hope that helps.
