So here's something I stumbled upon. During the mid/late 80's, the 49'ers used different fonts on the same jersey. I found the font shown on the PSI jersey. The only images I could find of it though always show it on the back of the 49'ers jerseys. The front always seems to have the snub-nosed style. That is to say, I couldn't find any images of the "gradual" style on the front, regardless of year or player.
See image below.



Here's an additional little nugget:
Below is a 1988 Montana, auctioned off by Lelands in August of 2001.
The description read:
"The Finest Joe Montana Game Worn Jersey Ever Offered
Incredible Montana white mesh is signed on the well-worn numbers with "Russell Athletic [size] 44" tagging. Amazingly, it includes photo evidence of game wear and 1988 LOA from Bronco Hinek, the 49ers Equipment Manager. Worn in the historic 9-11-88 game versus the New York Giants at the Meadowlands. Montana threw a last minute 78-yard touchdown to win the game 20-16, paving the way towards their third Super Bowl Championship. Comes with a videotape of the game showing Montana being pushed to the turf clean and getting back up with the tell-tale white marks that appear on the top of the front's "1". Also includes the white tape used by Hinek to mark the game the jersey was used in, and the Sports Illustrated article showing him wearing the jersey (same white mark). This is the only known road white Montana jersey that can be tied to a game with video & photo evidence and a team letter.
Price Realized: $15,852.65
- Interestingly enough the Montana below seems to also show the snub-nosed font in front and gradual font in back.
