Same old question. Who did what and who was first.
Carr came up with the Arcitectura and made it free: Freeware! from A. Carr Remember to vote! If you don't vote, you can't bitch! - Fantazia Fonts and Sounds. But: Fantazia, a cloner.
Fonts.com decided to try to sell an ICG version for $42, as Arquitectura: Copyright (c) 1992 Image Club Graphics, Inc. But: no designer info
And then we have the Corel Architecture: Copyright (c) 1992 Corel Corporation. Also no designer info.
Most probably there are also BT and URW versions around. And I would not be surprised if even Adobe would claim claim it to be a Adobe design.
Heron probably knows. She's much better at this.
I've already tried myfonts.com/what the font?
it's for one of my clients and they have no idea???!!
