TGL 31034-2 by Peter Wiegel is a free narrow sans serif with the measured look of technical lettering. Its tall, narrow letters lean forward with an even, lightly drawn stroke. Curves are spare and controlled.
Industrial subjects are the clearest setting for this disciplined lettering. It suits engineering exhibits, transport posters, and archival publishing, where the compressed proportions recall drafting. On machinery-themed packaging, the letterforms can become part of a diagram or marking rather than neutral text.
