Working towards compromise!

As most people who have co-habitated know, there are differing opinions to what decor goes up.  I had my "girly" apartment when I lived my last year in Boston knowing it might be my last.  I LOVED it!  My current SO had his little apartment and it was covered with these vintage military posters.  So here we are in this small 980 sf house and he wants to put all 4 up.  They are HUGE!  I agreed that I could put my 4 vintage horse frames up in one corner or something and he could put one up in the main rooms and 2 up in the office, if he didn't also want to put up his awards.  We have agreed that we will buy a lot of new frames and do some cool cluster frames in the LR and possibly DR.  One of the prints means a lot to him because he grew up with it in his basement and it is the same one his Dad has.  His Mom was lucky, they had a basement :)  I like them, I just don't want them all up.  Any advice???  Here are some pictures of his posters and my old apartment. 

I apologize for the quality of the photos.  As you can see they are just sitting on the floor or somewhere right now. 

Here are 3 of the 4 prints as well as my Boston apartment.  Thanks to Rachel and Rebecca for convincing me to buy that green couch.  I would get it again, but maybe in dark grey but I LOVED the green for that white apartment. 

You can see the horse photos that he hates in my old apartment photos.  I could fit all 4 in one of his prints :)
