Table Number Photo Cards Vs. Year Dated Photo Cards

So my original plan was to have table number signs 1-20 (or however many tables we have) and I saw in a magazine somewhere a couple who had put an image for example of both of themselves when they were 7 years old on 'table card 7' - Like this:

But Then just recently I came across another cute idea! Where instead of the age as corresponding with the table number - you make the table number the year i.e. 1987 and then you put a photo of both of you that year! I like this idea as it emphasizes the DATE/YEAR theme (and the 1989 etc. sounds neat and unique and goes along with the 'old fashioned' / 'past' theme of the wedding).

However the downfall is that Ben and I are not the same age - So we would have to start with 1987 (and would miss having photos of Ben at 1 and 2) AND since he's two years older than me we would also always be a different age in each photo!

So I need advice on what you think! Stick with the Age as corresponding with the table number OR take the more unique route and make the table # ayear's date with a photo of us in that year? Here is an example and these two people don't look to be the same age either?!? So do you think it would work? - Please leave a comment on this post if you have any insight!! :D Thanks
