'Fraid I can't supply pics, 'cause the operating system on my ancient iPhone no longer talks to the OS on my laptop. But I have also been working hard on boosting the artwork in my house and it goes like this (in descending order of feeling flush):
Original artwork (paintings, drawings) by actual professional artists - not as many of these as I would like, because, you know, money.
Limited edition prints by proper artists - these range from £40 to £180 and I would probably spend another slice on getting them framed. Framing can add £100, so I have to really like the piece.
Paintings, drawings, photos by DS (on fine art foundation year) - sometimes flash the cash for proper framing, sometimes use ready-mades from Etsy.
Posters and prints linked to events and holidays we've enjoyed, usually sourced from museum/gallery shops.
Charity/vintage shop finds. I have some pictures which I found at a recycling centre - one person's trash being another's treasure.
Postcards, pages from children's books, wallpaper samples, - usually I can frame these with readymade from Etsy, or repurpose a frame from one of my charity shop/skip diving finds.
I've got a ticket for a vintage poster fair for next month, and hoping to pick up something from there. And the art school end-of-year shows should be running again from this year.
I'd love to do more, and more quickly, but it does cost a bit, and I find it's better to collect several pieces that sort of hang together in some way - colour, medium, subject, frame - and then 'do' a wall or a section of hallway or staircase or whatever so that it feels completed. Also, I'm horribly indecisive, and it can take a long time to work out what I want.
Good luck, enjoy it!
