In my opinion.
The Art of the Polish in terms of being produced as theatrical release posters really came to end in the early 90s, after the fall of communism. It's not entirely the case as some were still made for art houses in Poland by those cinema instutions that were still showing specialist films, but Hollywood did come to dominate polish poster production from there on, and posters have become just photomontage based on the studio images - mostly boring.
Some artists continued with their art by producing posters for specialist cinemas and film societys, and not forgetting theatre and opera (big in the 90s) and the likes of festivals and exhibtion posters. These I would not class as commercial posters as they are produced for screenings and were often produced in limited editions to sell through galleries and for export - but in very small quantities (300-500). There were a handful of artists like Wieslaw Walkuski who continuted to produce much work this way during the 90s and much of it is very well respected work.
In the early 2000's and particulary now in the last few years we have seen a lot of new contempary artists producing art prints (simarly perhaps to Alamo drafthouse / Mondo concept) of posters inspired by films. These are commercial posters but agains prodcued in limited qualities of 300 I think aimed at both the home and the foreigh collectors market. I don't see anything wrong with this as they are still not mass produced and still collectable.
In the last few years we have seen Krzysztof from Polishposter.com has been working with both new artists in producing and printing a bunch of new posters as the old stuf is getting harder and harder to get hold of, we have seen some interesing work and you can see it at

I quite like a lot of it but I think I would only buy the odd one or two as they are I suppose not theatrical and if you own collect theatrical then you wouldn't be interested in these. But I do have quite a few like these couple of examples as I really like them.
Love this one but not bought it yet.
And these two which i have amongst many others. I think they are fine examples of new work produced outside of the cinema distribution of posters which is now entirely dominated by Hollywood, but at least they are limited and a great way for artists to keep on producing new work.
Finally, we have seen a few previously hard to get posters reprinted in limited editions (often with signed copies being available), which are great for these classics which are hard to find, which you can now buy (officially printed in collaboration with the artists - some with signed editions). Like these gems. And I am sure these titles wiil need no introduction.
This new limited reprint of 50 signed sold on emovie for $88 but you could buy it for $30 if you know where.
These next two are quite big editions of 1000 (offset prints) but I believe there are very small quality of signed APs. Now whether one things this is a good or bad idea is down to the individual. They are after all official licenced editions and its a chance to own the art without having to spend a few hundred.
Interested to see what people think.
