When I saw BF at Gröna Lund amusement park (or tivoli) in Stockholm three years ago I brought home a couple of nice 50" x 70" posters advertising the gig. These were graphic images (like colour drawings) of BF, rather than photos, and were very reasonably priced (at somewhere between a fiver and a tenner, from memory).
When I saw a similar poster online for this year's gig (which I'd planned to attend), I was disappointed that they wouldn't be for sale at the venue. I therefore googled the artist and contacted him in the USA directly, but his conservative estimate for one poster, including shipping to the UK, was an eye watering $450!
It was therefore a pleasant surprise when the venue subsequently decided to put a large number of band images online and to make them available for downloading free of charge.

If this link should take you to the full menu, just put BF's name in the search field:

I went to my local Snappy Snaps, who quoted me £8 per item in A4 size or £16 in A3; other sizes up to 50" x 70" are apparently available.
(*The hawk-eyed among you will notice that the 2020 graphic (for the gig rescheduled into 2021) bears the 15/6 date of the 2017 gig...
