Slightly different perspective:
I worked for a school that offered a Bachelor’s degree in Graphic Design. The school made every effort to find work for each graduate.
While most of the graduates were indeed in their 20’s, quite a few were in their 30’s, 40’s and even 50’s or above.
As NEW graduates, knowing all of the programs and software, the older students probably had fewer problems finding work - but they did indeed have to start at the low paying, entry level.
Employers would look at the portfolios before even scheduling an interview - so this helped a lot. The students were being judged on their work before they even met for a face to face interview.
Now granted, the young, hot looking girl, or cool looking young dude, would often find it easier to find work - but I think this is true in ANY field. But otherwise, as new graduates simply submitting portfolios for job applications, I think it was pretty fair across the board, regardless of age.
But as mentioned, these students (no matter the age) had just learned the newest of the newest of everything, and could jump in and do anything the employer was looking for, as well as bring in some fresh new ideas.
Now, it could be that once the student arrived, and they realized the candidate was 53 years old, they might have been surprised - but for these entry level jobs, I doubt it made any major difference at that point.
As far as 5, 10 years down the line, well - that is another question. I can only hope the older students kept current and the employers were happy to have someone reliable and up to date on the staff.
