An ad for the annual Variety Club Convention appeared in the March 18, 1940 issue of “The Film Daily.  The main headline was hand lettered in a classic Art Deco “solid” style of sans serif - ultra bold and with no counters - but had one additional feature: ‘engraved’ lines to the left of each character.

This has now been expanded into the digital typeface Trade Convention JNL, which is available in both regular and oblique versions.

Variety Clubs (now know as Variety - The Children’s Charity) was founded in Pittsburgh, Pennsylvania in 1928 by entertainers specifically to aid children.  Their history can be found at https://variety.org/who-we-are/history
