Am not great with sizes and have no measuring tape. Just had a look at one that is here on the bedroom floor and not put up yet!!!
2 of the prints were approx 15 inches x 13 ....they worked out at 58 each, I think. The two bigger ones, one was about 2 ft x 2 and the other slightly smaller were approx. 120-130 each from what I recall.
Looking at the bigger ones now now they are both double mounted, cream over black with a chunky black frame and you can see the quality.
I am not sorry I had the bigger 2 custom framed, but just to compare, I got a black frame for a similar size print to the smaller ones, for 14 in IKEA.
Also, I could have picked cheaper frames if I wanted to. The ones I picked were mid range.
