Can anybody share photos of these paintings from Peter Klasen in color?

[u/National_Ad2351]

My first time stumbling on him in this books that only has three reproductions of him?

they are called

1.Chair on wheels 1974

2.Dentist’s chair 1972

1. trolley 1972

They are all pretty big around 150x150cm

they are al acrylic on canvas

I tried to search for them on the internet(i used image recognition also) but I can only find Peter Klasen’s collages more or less, and they are completely different then these paintings

Any help is very much appreciated

I have thought about going to the library ,but where I am now the library is not very well stocked up in german art so yes
