Big prints - Advise needed

[meng]

I'm planning to enlarge one of mine 2MP A40 shots to either A2 or A3 size to a jigsaw puzzle.
Should I maintain at 150dpi that is to interpolate the image or reduce to about 75dpi to give an image of about close to 1600 x 1200, the image as given by my cam?
Anyone can give advise on this?

Interpolate and push to at least 200 dpi. That's what I did for the sepia Ubin shot you saw.

Give it a shot. I'm sure you'd see the pixelation (if bad) on screen first.

Here's the copy saved in jpeg in the highest setting, in 200dpi.

Looks okie top me, but I'm only afraid of the results.
what do you think?

P.S: not editing done yet and I have posted the link instead of the whole photo as not to delay the loading time for this thread.
