I didn't see a "Airport Play Set" category, so - here we are. I was reading about the various Dinky and Corgi aerodrome GSE pieces with great envy! However, all I have to post are some more recent sets.
As you know these days there are a great number of airport play sets that you can buy. By far the most common are the Daron sets which feature most of the world's airlines and which are sold by same. Daron didn't start this genre, the sets they sold were first made by RealToy - and probably still are - just under the Daron name. As usual the GSE is way overscale for the airplane, and as with all RealToy product the airplane is mostly plastic, although it looks good and the various markings are done well.
I am adding their Continental 757 set here as an example.
That said the next frame shows an oddly similar packaging with similar GSE but from the middle '90s. This is a Tomy (Tomica) airport play set and I can assure you that the 747 is a beautiful piece - all metal - and a world better than the RealToy and Daron pieces! They also made a set with an L1011.
I'll post these before moving on...these Tomica planes are very nice!
So, is this just a case of copying a successful package, or did RealToy and Daron simply acquire and expand on the Tomy sets? ...probably the latter. The Daron issues of these play sets are diverse and offer good play value, although the airplane itself is of little interest to us. Naturally, this very common Continental issue is now of more interest since that airline has disappeared into UAL!
